Hi all, Is it possible to run libvirt API on arm hardware platform? (i,e. armv7) Or any work done to work around it? Thanks Gavin

[libvirt-users] Problem booting guest with more than 8 disks
by Jon 03 Dec '13

03 Dec '13

Hello All, On my host machine, I'm using kvm, libvirt, ceph and ubuntu versions as follows: >> QEMU emulator version 1.5.0 (Debian 1.5.0+dfsg-3ubuntu5), Copyright (c) 2003-2008 Fabrice Bellard >> root@kitt:~# virsh --version: 1.1.1 >> ceph version 0.67.4 (ad85b8bfafea6232d64cb7ba76a8b6e8252fa0c7) >> VERSION="13.10, Saucy Salamander" >> Linux kitt 3.11.0-13-generic #20-Ubuntu SMP Wed Oct 23 07:38:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux I'm encountering an issue when attempting to boot a VM with more than eight disks, the boot disk is not found and the vm fails to boot with an error "No bootable device". This happens with Archlinux, Ubuntu. and Fedora images. I'm working on a tool [1] to build virtual machines, it creates rbd images named $hostname-os and $hostname-storageX (where X is the "additional disk number" starting at 0, a vm with seven disks would have one named -os and six named -storage{0..5})--the os disk is a clone of a protected COW RBD snapshot--the the tool defines the xml and uses Sys::Virt to define and boot the virtual machine. All os types use grub, ubuntu and fedora use an mbr and arch uses gpt, I'm not certain that matters as vms with less than six disks boot no problem. I've included both my generated and dumped xml for both my booting and non booting vms. The only consistent difference between the vm deployments is the addition on $hostname-storage6. Is there perhaps a way to specify which hd is the boot device? I appreciate any assistance. Thanks, Jon A [1] https://github.com/three18ti/Build-VM non Booting VM: ######################################################### # Generated: | <domain type='kvm'> | <name>arch_test2</name> | <memory

[libvirt-users] virsh detach typo
by Mauricio Tavares 03 Dec '13

03 Dec '13

[root@vmhost vms]# virsh detach-disk puppet vdb error: No found disk whose source path or target is vdb [root@vmhost vms]# virsh --version 0.10.2 [root@vmhost vms]# This probably was solved already but if not, "No found disk" probably sounds better if it was "No disk found"

[libvirt-users] Does virsh support offline migration?
by me,apporc 03 Dec '13

03 Dec '13

I saw some docs referred one option "--offline" for "virsh migrate" on the internet, and there was one section called "Offline Migration" in libvirt.org, but i did find this option on my local machine. So, is it libvirt really support offline migration ? Is that because my libvirt is a little older? Is that option "--offline" right? -- Regards, apporc

[libvirt-users] FYI: Wiki account self-registration disabled
by Daniel P. Berrange 30 Nov '13

30 Nov '13

Unfortunately evil spammers have managed to defeat all the anti-spam measures we've tried with the wiki. So it is with regret that we have had to disable new wiki account self-registration. We do still welcome contributions from anyone interested in adding wiki content. We just ask that you send a mail to the main devel mailing list (libvir-list(a)redhat.com) to request an account be created for you by the wiki admin. Meanwhile we're hoping to migrate the wiki to new hosting service where we'll be able to deploy newer wiki software and thus hopefully better anti-spam measures. When this happens we'll look at re-enabling self-registration of accounts.

[libvirt-users] Help required in simulating libvirt TLS server
by Arun Viswanath 26 Nov '13

26 Nov '13

Hi All, Will some one explain how is this tls libvirt server is implemented. For my testing purpose I need to implement the similar TLS server in Java or Python and this server is capable to receive all libvirt calls like getCapabilities, hostname etc and return response as I'm configured. Basically I need to simulate the libvirt TLS server. I tried creating many TLS server but none of the my TLS server implemenation is capable to do proper handshake with python libvirt client and do successful calls. Any ideas or help will be appreciable. Thanks In Advance, Arun V
