by Frank Murphy 19 Jul '10

19 Jul '10

I have some guests (one in particular) I need to check the fs, which are luks encrypted. Can someone point me right, have installed guesfish? but have always been lost with "man x" unless specific examples gives. Host is luks except /libvirt/images (/dm0) But the guests on it are luks. -- Regards, Frank Murphy UTF_8 Encoded Friend of Fedora

irqbalance required for CentOS-5.5 in F13
by Björn Sund 19 Jul '10

19 Jul '10

Is this a bug or feature? Worked fine without it in previous versions. Not 100% sure it is just irqbalance, but when doing minimal installs the VM would crash after some time running. Installed acpid with no result and then irqbalance and it would run fine. regards

Fedora 14 ========= Fedora 14 development is moving along and we are getting very close to the feature freeze. If you have a pending feature, it needs to be in and ready for testing as soon as possible. 2010-07-27 Feature Freeze (12 Days) 2010-08-03 Alpha Freeze (19 Days) 2010-09-07 Beta Freeze (54 Days) 2010-10-12 Final Freeze (89 Days) 2010-10-26 Fedora 14 Release (103 Days) Fedora 13 ========= Just a note that we have a few virtualization packages in updates-testing. Please test and provide karma in bodhi as appropriate. Fedora Cloud SIG ================ Progress is being made towards updated Fedora in the EC2 cloud, and There is some interest in supporting other cloud environments. More details can be found at https://fedoraproject.org/wiki/Cloud_SIG Virt Preview ================ As was announced before, the virt-preview repository for F12 users wishing to test out the latest F13 virtualization bits is available. Additionally we have created a virt-preview repository for F13 users wishing to test out packages destined for F14 virtualization. Instructions for using these repositories can be found at: https://fedoraproject.org/wiki/Virtualization_Preview_Repository Recent updates in this repository include: F-13: ==== libguestfs-1.5.0-4: - New development branch 1.5.0. - Remove two upstream patches. - Work around permanently broken test-getlogin_r Gnulib test. libvirt-0.8.2-2: - CVE-2010-2237 ignoring defined main disk format when looking up disk backing stores - CVE-2010-2238 ignoring defined disk backing store format when recursing into disk image backing stores - CVE-2010-2239 not setting user defined backing store format when creating new image - CVE-2010-2242 libvirt: improperly mapped source privileged ports may allow for obtaining privileged resources on the host - Upstream release 0.8.2 - phyp: adding support for IVM - libvirt: introduce domainCreateWithFlags API - add 802.1Qbh and 802.1Qbg switches handling - Support for VirtualBox version 3.2 - Init script for handling guests on shutdown/boot - qemu: live migration with non-shared storage for kvm python-virtinst-0.500.3-4: - Drop default CPU config, fix some 64bit installs (bz 611584) - If host is 64bit, make sure VM always sees 64bit CPU (bz 611584) - Keep windows CDROM attached for second install stage - Fix pool source listing in virt-manager F13 Bugs ======== DOOM-O-METER: 33 bugs are open against F14 virtualization packages, but it is rather early in the cycle. 118 bugs are open against F13 virtualization packages. We need to spend a bit of time focusing on these. If you would like to help out, you can find more information at: http://fedoraproject.org/wiki/Virtualization_bugs = Important = == kvm == https://bugzilla.redhat.com/show_bug.cgi?id=605757 2tb virtio disk gets massively corrupted filesystems This issue should be resolved in the next qemu update for F13. https://bugzilla.redhat.com/show_bug.cgi?id=613517 Guest machine is stuck (no ping, no nothing) (host spends 25% in read_hpet) This should be fixed with the latest seabios update in F13 updates-testing.

The UI you are using is virt-manager. virt-manager uses libvirt to list all USB devices on your host machine. The 'add hardware' wizard let's you expose any USB device to QEMU/KVM (the emulator which actually does all the heavy lifting). So yes, virt-manager/libvirt can handle USB 2.0 However, QEMU does not know how to take that device and make it appear as a USB 2.0 device to your VM OS: it can only expose it as USB 1.1 for all QEMU versions in Fedora. Most devices can fallback to USB1 mode though, so I'm not positive if that is why the device isn't showing up in your guest. > When will qemu support USB 2.0?

Then again I don't know the QEMU code very well. Did you test passing through another USB device? That should help narrow it down. - Cole

Firstly, make sure you are running the latest fedora packages, since there have been some USB fixes within the past month. Your config looks fine. Does passing through any other device work, like a USB memory stick? Some of the newer ipods might require USB 2.0 which Qemu doesn't support.

network services not working properly in a vm?
by Kenneth Armstrong 12 Jul '10

12 Jul '10

I have 2 RHEL 5.5 VM's on a Fedora 13 host, using Default (NAT) networking. I can ssh into these fine, but when I install services such as DNS, NTP, FTP, etc. and open their respective ports in the guest's firewall, the guest acts as if their closed still.I ran nmap against my guests, and they show that the ports are there, but closed (as in below): PORT STATE SERVICE 21/tcp closed ftp 22/tcp open ssh 53/tcp closed domain 631/tcp closed ipp MAC Address: 52:54:00:5A:B3:E4 (QEMU Virtual NIC) Is there something else I'm supposed to be doing to make this work with my guests?

Adding tgtd iSCSI LUNs on the fly
by Ewan Mac Mahon 12 Jul '10

12 Jul '10

Hi, This isn't strictly a virt question, but I hope it's related enough that this is a sensible place to ask it. I've got a small libvirt/KVM setup (on F13) that uses a separate storage box (on RHEL/SL 5.4) running tgtd to export iSCSI storage consisting of a single target with one (LV backed) LUN per VM. The storage is all configured in /etc/targets.conf. If I add a new LUN to the configuration file and then try to make it live by doing: tgt-admin --verbose --execute I simply get a message saying that the target already exists (which it does) and the LUN isn't added. I can, however, add the LUN manually by doing something like: tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 5 -b /dev/VGstorage/LVkvm-vm5 So, in short, is there a better way of doing this that will sync the running configuration from /etc/targets.conf, including picking up changes to a target rather than just new targets? Ewan

[ANNOUNCE] libguestfs 1.4.0 - tools for accessing and modifying disk images and virtual machines
by Richard W.M. Jones 08 Jul '10

08 Jul '10

I'm pleased to announce a major new release of libguestfs. libguestfs is a library and a set of tools for accessing and modifying disk images and virtual machines. You can use this for viewing and editing files inside guests, scripting changes to VMs, monitoring disk used/free statistics, P2V, V2V, performing partial backups, cloning VMs, and much more. Home page: http://libguestfs.org/ Downloads: http://libguestfs.org/download/?C=M;O=D Release notes for libguestfs 1.4.0 ---------------------------------- These release notes only cover the differences from the previous stable/dev branch split (1.2.0). For detailed changelogs, please see the git repository, or the ChangeLog file distributed in the tarball. New features - guestfish lets you choose a prepared disk image, eg: guestfish -N fs:ext4 - Add write support to guestmount (FUSE) module. - virt-resize can now resize the content of partitions and logical volumes in the guest, and we have better support for shrinking guests. - Bash tab-completion script for guestfish. - Add ZFS support to virt-rescue. - New tool 'virt-make-fs' for creating filesystems with content. - Allow suffixes on any guestfish number parameter, eg. "1M". - guestfish 'man' command opens the manual page. - guestfish supports a "heredoc" syntax for uploading files: upload -<<_end_ /foo content _end_ - Some guestfish commands now print their output in octal or hex where appropriate (RHBZ#583242). - Allow dash prefix on guestfish command line. This ignores any error from the second command: (RHBZ#578407) guestfish -- cmd1 : -cmd2 : cmd3 - guestfish -h / help command now returns an error for non-existent commands (RHBZ#597145). - New 'supported' command in guestfish to list optional groups of commands which are supported by the daemon / configuration. - virt-inspector and guestfish -i now work for filenames which contain spaces (RHBZ#507810). - Change the protocol to use link-local addresses, to avoid conflicting with any address that the host might be using (RHBZ#588763). - libguestfs now sets the correct time and timezone on filesystem modifications. - Sort the domains into alphabetical order in virt-df. - Make mkfs-b command work for FAT and NTFS by mapping the blocksize parameter to the cluster size (RHBZ#599464). - Add version numbers to Perl modules (RHBZ#521674). - Localization now works for all the libguestfs tools (RHBZ#559963). - Tools now support filesystem-on-image VMs (RHBZ#590167). - virt-list-partitions has a '-t' option to show the total size of disks. - Include extra Augeas lenses in the supermin appliance (Matthew Booth). - Add error and close callbacks. - Add explicit close method in the Perl API. - Multiple fixes for RHEL 5 compatibility. - Multiple fixes for Debian/Ubuntu compatibility. - Multiple revisions to improve the documentation. Security - Fix a potential DoS in virt-inspector and virt-v2v if a specially crafted disk image contained a char device in place of one of the configuration files that we read under /etc (RHBZ#582484). New APIs - aug-clear - clear Augeas path - available-all-groups - return a list of all optional groups - base64-in - upload base64-encoded data to file - base64-out - download file and encode as base64 - checksum-device - compute checksums on the contents of a device - checksums-out - compute checksums of multiple files in a directory - debug-upload - upload a file to the appliance - fallocate64 - preallocate a file in the guest filesystem - fill-pattern - fill a file with a repeating pattern of bytes - get-umask - get the current umask - lvresize-free - expand an LV to fill free space - ntfsresize - resize an NTFS filesystem - ntfsresize-size - resize an NTFS filesystem (with size) - part-del - delete a partition - part-get-bootable - get the bootable flag of a partition - part-get-mbr-id - get the MBR type byte of a partition - part-set-mbr-id - set the MBR type byte of a partition - pvresize-size - resize a physical volume (with size) - pwrite - write to part of a file - resize2fs-size - resize an ext2/3/4 filesystem (with size) - txz-in - unpack compressed tarball to directory (RHBZ#580556) - txz-out - pack directory into compressed tarball (RHBZ#580556) - vfs-label - get the filesystem label - vfs-uuid - get the filesystem UUID - vgscan - rescan for LVM physical volumes, volume groups and logical volumes - write - create a new file - zero-device - write zeroes to an entire device Internals - Extend the generator to support testing optional features. - Stricter checks on input parameters to many calls (RHBZ#501893 RHBZ#501894) - Extend the protocol to support sending arbitrary 8 bit data buffers. - Ship 'BUGS' file with releases. This is a summary of the bugs in the Red Hat Bugzilla database. - Ship 'RELEASE-NOTES' file with releases, containing release notes. - Unify supermin appliance building into one place, in febootstrap 2.7. - Fix the protocol code to handle the case where both ends send cancel messages at the same time.
