Re: [fedora-virt] Routing to guests

Alexander is correct in saying that bridging would allow you to do that. There are two networking discussed in the guide. The first is a NAT (network address translation), in which the guests are given "private" ip addresses and any outbound traffic appears to be coming from the host machine's IP address. This is the same as the setup on your ADSL router where the internal network machines get addresses of 192.168.x.x but the internet sees your requests as coming from the IP address of your router. There should be lots of documentation in linux firewalling guides under sections on NAT (or possibly called IP Masquerading in some). Have a look at these for information on port forwarding to reveal services inside the virtual (such as ssh). The other option is bridging. This shares the physical network interface of the host with the guest. In this case the VM acts as though it's a machine plugged into the same subnet as the host, its services are accessible like those of the host and it's as vulnerable to attack as the host. Robert

virt-preview for Fedora 15 users back in sync
by Justin Forbes 23 Sep '11

23 Sep '11

For those of you using the virt-preview repository for Fedora 15, binutils was updated, which allowed me to build seabios and put the rest of the stack in sync. You should notice updates on most packages today, and things will stay in sync with F16 moving forward. For those of you not using virt-preview, who might want to run the latest/greatest virt stack from Fedora 16 on a Fedora 15 host, instructions are located at: https://fedoraproject.org/wiki/Virtualization_Preview_Repository Thanks, Justin

CentOS 6 install via virt-install - "No usable disks have been found."
by Bill McGonigle 17 Aug '11

17 Aug '11

Hi, all, I'm not seeing disks under CentOS 6 when trying to install. I'm using: xen-4.0.2-1.fc14.x86_64 2.6.32.39-175.xendom0.fc13.x86_64 installing using: virt-install --debug -n sully --mac=02:00:0A:01:01:10 -f /var/lib/xen/images/sully -s 12 -r 2048 --vcpus=2 --nographics -p --os-type=linux --os-variant=rhel6 --location http://librescu.bfccomputing.com/cobbler/ks_mirror/centos6-x86_64/ It sounded like: https://bugzilla.redhat.com/show_bug.cgi?id=678374 so I tried dropping the --nonsparse option, but I'm using a newer version of python-virtinstall: python-virtinst-0.500.6-1.fc14.noarch than should be required, and I'm seeing this with and with the option anyway. I do see the disk image is created, and attached to the DomU. e.g.: [2011-07-26 01:01:47 18534] DEBUG (DevController:97) DevController: writing {'domain': 'sully', 'frontend': '/local/domain/18/device/vbd/51712', 'uuid': '3380cea8-a322-292d-cc5d-8bb084306976', 'bootable': '1', 'dev': 'xvda', 'state': '1', 'params': 'aio:/var/lib/xen/images/sully', 'mode': 'w', 'online': '1', 'frontend-id': '18', 'type': 'tap'} to /local/domain/0/backend/tap/18/51712. and I can see the disk image if I dump configuration from virsh. I do see this in the DomU kernel messages: XENBUS: Device with no driver: device/vbd/51712 XENBUS: Device with no driver: device/vif/0 XENBUS: Device with no driver: device/console/0 but I see reports online that say not to worry about those, initrd will load the modules. The initrd does have: ./kernel/drivers/xen ./kernel/drivers/xen/xenfs ./kernel/drivers/net/xen-netfront.ko.gz ./kernel/drivers/block/xen-blkfront.ko.gz on it. I tried adding: xen_emul_unplug=never to the kernel parameters per a previous thread here, but that didn't seem to change anything. It seems like others are having success with CentOS 6 in general: http://grantmcwilliams.com/tech/virtualization/xen-howtos/538-centos-6-virt… so I suspect it's got something to do with Xen 4.0.2, but I'm not sure where to look right now.

FYI: libvirt doesn't see any qemu/kvm install options on fedora rawhide
by Cole Robinson 23 Jul '11

Just a heads up: apparently an issue in our rawhide qemu package is breaking libvirt capabilities reporting, which prevents virt-manager from creating new VMs and lot's of other problems with libvirt: https://bugzilla.redhat.com/show_bug.cgi?id=724814 - Cole

Fedora Virt Status
by Justin Forbes 22 Jul '11

22 Jul '11

Fedora 15 - We have 65 open bugs 11 of which have fixes in awaiting updates. - 12 bugs have been closed in the last week Fedora 16 Fedora 16 Feature Freeze is just 1 week away. It is time to make sure things are in shape for alpha. Important dates for the Fedora 16 Schedule: 2011-07-26 Feature Freeze--Planning & Development Ends 2011-07-26 Branch Fedora 16 from Rawhide-- Branch Freeze 2011-08-02 Software String Freeze 2011-08-02 Alpha Change Deadline 2011-08-16 Alpha Release 2011-08-30 Software Translation Deadline 2011-09-06 Beta Change Deadline Features 100% Complete 2011-09-20 Beta Release 2011-10-10 Final Change Deadline 2011-10-11 Compose 'Final' RC 2011-10-25 Fedora 16 Final Release == Updates Needing review == The following packages are in updates-testing and need review and karma as appropriate: F14: - libvirt-0.8.3-10.fc14 CVE-2011-2511, integer overflow in VirDomainGetVcpus - libguestfs-1.8.9-1.fc14 Stable branch update to version 1.8.9 F15: - libguestfs-1.10.5-1.fc15 Update to stable branch version 1.10.5. - spice-protocol-0.8.1-1.fc15 this package doesn't close any bugs but it is required to build an updated spice-server that will close bugs. == Virt Preview Repository == The virt-preview repository is now active for F15 users wishing to run the latest F16 virt packages on their stable F15 systems. F14 virt-preview users will still get the latest F15 packages. For details on how to run enable virt-preview, please see: https://fedoraproject.org/wiki/Virtualization_Preview_Repository At the moment, virt preview is out of sync with F16 due to a bug in binutils which will not allow the new seabios to build. Because libvirt requires the newer seabios, updates have been put on hold until the binutils fix is pushed to Fedora 15. == Bugs of importance: == - 700560 F15 virt-manager gui locks/freezes in the default storage pool There is a bug which states that sym-linked storage pools will lock virt-manager, and now reports that the default storage pool does as well. - 720995 F15 kvm gets stuck while booting 32 bit guest on 64 bit host with smp This seems to be the kvmclock regression bug, and the patch will make the next update

Xen dom0 / Fedora 16 Schedule Reminders - Feature Submission and Feature Freeze

Hello, Is someone currently working on Xen dom0 support for Fedora 16 ?
