On a gentoo server with libvirt-1.1.3 I get problems with starting VMs. When I do: # virsh start vm180 error: Failed to start domain vm180 error: Input/output error This happens with 1.1.3 and 1.1.4 (I rebuilt the packages and restarted the libvirtd.service). # journalctl -f -u libvirtd.service shows: Dec 03 17:32:56 jupiter libvirtd[24020]: Input/output error Dec 03 17:33:47 jupiter libvirtd[24020]: Input/output error The log for the specific VM shows: 2013-12-03 16:33:47.004+0000: starting up LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin QEMU_AUDIO_DRV=none /usr/bin/qemu-kvm -name vm180 -S -machine pc-i440fx-1.5,accel=kvm,usb=off -cpu Opteron_G5,+bmi1,+perfctr_nb,+perfctr_core,+topoext,+nodeid_msr,+tce,+lwp,+wdt,+skinit,+ibs,+osvw,+cr8legacy,+extapic,+cmp_legacy,+fxsr_opt,+mmxext,+osxsave,+monitor,+ht,+vme -m 3954 -realtime mlock=off -smp 4,sockets=4,cores=1,threads=1 -uuid 646f757f-2ab7-4fdf-2140-a79396200c6f -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/vm180.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=localtime,clock=vm,driftfix=slew -no-kvm-pit-reinjection -no-hpet -no-shutdown -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -drive file=/dev/VG01/vm180_disk0,if=none,id=drive-virtio-disk0,format=raw,cache=none,aio=threads -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x7,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -drive file=/mnt/tests/grml64-full_2013.02.iso,if=none,id=drive-ide0-1-0,readonly=on,format=raw -device ide-cd,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -netdev tap,fd=27,id=hostnet0,vhost=on,vhostfd=28 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:8d:3b:af,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -vnc 127.0.0.1:5 -vga cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x6 2013-12-03 16:33:47.013+0000: shutting down libvirt: error : libvirtd quit during handshake: Input/output error What can I do about this issue?

[libvirt-users] layer2 tunnel between guests across hosts
by sujay g 03 Dec '13

Hi, Is it possible to setup layer2 tunnels between guests across hosts? Using vrbr? -- i.e the Guest is unaware. On Host 1: guest (a) --- vrbr0 ------- | | On Host 2: | guest(b) -- vrbr0 ------ Has there been any work done around it? TIA, -Sujay

[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 02 Dec '13

02 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 02 Dec '13

02 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 29 Nov '13

29 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.
