Do you mean the EPEL package or the contributed CentOS spec file (in contrib/)?

Hostdev XML Not Working (Libvirt)
by Robert L Cochran 27 May '09

27 May '09

Why doesn't the hostdev xml shown below for a USB device work? I've shown the entire <devices> block for context. <devices> <emulator>/usr/bin/qemu-kvm</emulator> <disk type='file' device='cdrom'> <target dev='hdc' bus='ide'/> <readonly/> </disk> <disk type='file' device='disk'> <source file='/var/lib/libvirt/images/Ubuntu9.img'/> <target dev='vda' bus='virtio'/> </disk> <interface type='network'> <mac address='54:52:00:74:32:2f'/> <source network='default'/> <model type='virtio'/> </interface> <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target port='0'/> </console> <hostdev mode='subsystem' type='usb'> <source> <vendor id='0403'/> <product id='6001'/> </source> </hostdev> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes'/> <sound model='es1370'/> </devices> The USB device of interest to me is an FTDI FT232RL chip. When I plug the board into a USB port on the host, I want it to be passed through to my Ubuntu guest so that it can be seen as /dev/ttyUSB0. The guest doesn't see it. I took the product and vendor id numbers from the /var/log/messages output, and these might be in hexadecimal (and I should be writing e.g. <vendorid=0x0403'/>. I might also be getting the physical handling of the device wrong: maybe it needs to be already plugged in at the time the Ubuntu guest is started up, or maybe I should start the guest first and then plug in the device? Advice appreciated. Bob Cochran

I checked in some fixes for CentOS to the git repo. I'll try to build an EPEL package later this afternoon.

Distributing Fedora 11 Created Virtual Machines
by Robert L Cochran 27 May '09

27 May '09

I have a virtual machine created on Fedora 11 which runs Ubuntu 9.04. I have some more customizations to do with the machine, such as getting it to speak to (FTDI 232R-based) USB devices. When that is done, I would like to copy the virtual machine to a USB flash drive and postal mail that to a teacher. The scenario I'm envisioning is that the teacher can then import the virtual machine and play it on his or her computer -- whatever that computer is, perhaps a Windows machine running VirtualBox or VMWare. Not necessarily a machine running Fedora 11, you see. Now we have my first question: can she run my virtual machine on another virtual machine manager, which is not necessarily a Fedora product? To go on with the story I'd like the teacher to add her customizations to the Ubuntu virtual machine, then she in turn will deploy that to students. They would copy the virtual machine to their computers (whatever those are) and play them on those computers. These will probably be whatever computers the school has an d/or whatever computers the student can afford to pay for. Could this work as well? Suppose the answer is no they cannot play a Fedora 11-created virtual machine on their own virtualization software. Is it possible to take the virtual machine file and clone (part of?) it to a hard drive such that Ubuntu can be booted from the hard drive? I'm having a wonderful time in the sandbox, playing with my Ubuntu guest. Bob Cochran

libguestfs - no ext3 support building on CentOS 5
by Charles Duffy 27 May '09

27 May '09

Howdy. CentOS 5's stock kernel has ext3 modularized; however, while make-initramfs.sh allows ext2.ko and ext4.ko modules to be included in the generated initramfs, no such exception is made for ext3.ko (or jbd.ko, on which it depends), leading to the following: ==== 5/140 test_zerofree_0 mount: /dev/hda1 on /: mount: unknown filesystem type 'ext3' test_zerofree_0 FAILED ==== Notably, ext4 is still ext4dev as of this kernel.

Successful Compile of libguestfs 1.0.31 in Fedora 11
by Robert L Cochran 26 May '09

26 May '09

I've been looking at the postings here more closely now that I have a Ubuntu guest running, and I decided to compile libguestfs-1.0.31 in Fedora 11. It took some time for me to get the dependencies installed. Question: what packages do I need for the ruby bindings? What package represents rake? How about OCaml bindings -- what packages are needed to get it to build? When building this file as part of `make`: initramfs.fedora-11.x86_64.img I got an awesome number of errors related to my not being the root user, but I assume those errors are okay since I built as an ordinary user. Also the perl documentation process came up with a large number of errors. After doing `make check` I got this result: Test boot completed after 10 iterations. PASS: test-bootbootboot.sh ================== All 2 tests passed ================== Am I ready for 'make install' -- is libguestfs built sufficiently well for that? Although I would like to get the ruby and OCaml bindings to build. Thanks Bob

Backport of zfs patches.
by Ruben Kerkhof 26 May '09

26 May '09

Hi all, I've hit a few issues with booting an Opensolaris domU (build 114) with the current Xen in Fedora. Would it be possible to backport patches hg19323 and hg19322? Otherwise I can wait for Xen 3.4 to hit rawhide, what's the timeframe for that? Kind regards, Ruben Kerkhof

Newbie Q? Mailing-List Support.

Is the mailing list support just for people who run guests on Fedora, or can it be used with Fedora Guest on CentOS Base? Thinking of putting a virt box or two together. FRank -- msn: frankly3d skype: frankly3d Mailing-List Reply to: Mailing-List Still Learning, Unicode where possible
