[libvirt-users] Backups failing due to snapshot already exists
by Phill Edwards 06 Jul '16

06 Jul '16

My VMs are raw disk images as logical volumes. My backup script takes a snapshot of a VM's volume, copies it off to another machine and then deletes the snapshot. For some reason I have a snapshot that didn't delete which is now preventing the backups from proceeding: ... Friday 1 July 02:10:01 AEST 2016: Taking snapshot of /dev/vms-lvm/MBE3-MythUbu-14.04-64bit.raw... ERR: The specified snapshot volume /dev/vms-lvm/MBE3-MythUbu-14.04-64bit.snap already exists. Operation canceled. ... But if I try to remove the snapshot volume I get an error that it's in use: $ sudo lvremove /dev/vms-lvm/MBE3-MythUbu-14.04-64bit.snap Logical volume vms-lvm/MBE3-MythUbu-14.04-64bit.snap in use. Can anyone please advise on how I find out what's using the snapshot, then kill that process so I can remove the snapshot so my backups can work again?

[libvirt-users] Virtual machine in state "in shutdown"
by Roland Everaert 06 Jul '16

06 Jul '16

Hello, We are currently facing a strange situation. One of our VM is shown by 'virsh list' as in state "in shutdown" but there is no more a qemu-kvm process linked to it. So we have a few questions: 1. What does means the state in shutdown (I have not found much information about it)? 2. How to cleanly "shutdown" the vm, or more correctly, clean the status in virsh/libvirt? Regards, Roland Everaert.

Hello, I am facing some problems in bridged networking. I have successfully created a bridge br0 and added a virtual machine to it. Now the address of virtual machine is 10.1.3.31.

04 Jul '16

Hello, Is there any command to list all available channels for specific machine? For example, i have a additional spice serial device: <channel type='unix'> <source mode='bind'/> <target type='virtio' name='com.redhat.kvm-vdi.0'/> <address type='virtio-serial' controller='0' bus='0' port='2'/> </channel> Is there any way to get full path to this socket on hypervisor side?

by Patrick Pichon 01 Jul '16

Hello, I have a problem which is that some of my VMs are loosing there IP addresses from time to time. What I saw in the log is when this VM loose its IP address there are DHCPREQUEST send from the VM by dhclient and the server responded only 50 minutes later ! Any help, advise on how to debug would be welcome.

by Patrick Pichon 01 Jul '16

01 Jul '16

Hello, I have a problem which is that some of my VMs are loosing there IP addresses from time to time. What I saw in the log is when this VM loose its IP address there are DHCPREQUEST send from the VM by dhclient and the server responded only 50 minutes later ! Any help, advise on how to debug would be welcome. Thanks in advance Patrick Here after is an extract from the log July 1st 2016, 05:08:46.156 zen.pipiche.net <http://zen.pipiche.net/> dnsmasq-dhcp DHCPREQUEST(virbr1) 10.10.0.10 52:54:10:7d:3a:3f

[libvirt-users] Windows guest and virtio serial port
by Tadas 01 Jul '16

01 Jul '16

I'm not sure, if it's correct mailing list to post this problem to. I'm having problems with Windows guest and virtio serial port. According to this manual: http://www.spice-space.org/page/Whiteboard/AgentProtocol I should get a named pipe on my guest VM after I create VirtIO sedial device and spicevmc channel. This works without any problems on Linux guest: ls /dev/virtio-ports/ com.redhat.spice.0 But on Windows guest I can see no such pipe: PipeList v1.01 by Mark Russinovich http://www.sysinternals.com Pipe Name Instances Max Instances --------- --------- -------- ----- InitShutdown 3 -1 lsass 4 -1 ntsvcs 3 -1 scerpc 3 -1 Winsock2\CatalogChangeListener-2b8-0 1 1 epmapper 3 -1 Winsock2\CatalogChangeListener-1ac-0 1 1 LSM_API_service 3 -1 TermSrv_API_service 3 -1 Ctx_WinStation_API_service 3 -1 eventlog 3 -1 Winsock2\CatalogChangeListener-174-0 1 1 atsvc 3 -1 wkssvc 6 -1 Winsock2\CatalogChangeListener-16c-0 1 1 SessEnvPublicRpc 3 -1 spoolss 3 -1 Winsock2\CatalogChangeListener-550-0 1 1 trkwks 3 -1 NlaSvcTask 1 -1 srvsvc 5 -1 browser 3 -1 Winsock2\CatalogChangeListener-710-0 1 1 Winsock2\CatalogChangeListener-228-0 1 1 Winsock2\CatalogChangeListener-230-0 1 1 HPUPDMon 1 1 MsFteWds 2 -1 PIPE_EVENTROOT\CIMV2SCM EVENT PROVIDER 1 -1 TDLN-3772-41 1 2 TDLN-3216-41 1 2 virtio serial drivers are installed on Windows guest VM.

[libvirt-users] pci slot increases after several times interface attach and detach
by Huanle Han 30 Jun '16

30 Jun '16

hi, I have a question about interface hotplug. I attach and detach interface from vm for several times. I find the pci slot of interface increases in live xml while keep unchanged in config xml. Here is my test script and result: Test Script: #!/bin/bash VM=ub1504b print_xml() { echo "$* : ========inactive===========" virsh dumpxml --inactive $VM |grep -A 20 "<interface" |grep "mac\|slot" echo "$* : ======== active===========" virsh dumpxml $VM |grep -A 20 "<interface" |grep "mac\|slot" } print_xml begin_ virsh attach-device --config --live $VM if1.xml print_xml attach virsh detach-device --config --live $VM if1.xml print_xml detach Result: begin_ : ========inactive=========== <mac address='0c:da:41:1e:02:9c'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> begin_ : ======== active=========== <mac address='0c:da:41:1e:02:9c'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> Device attached successfully attach : ========inactive=========== <mac address='0c:da:41:1e:02:9c'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> <mac address='0c:da:11:11:11:11'/> <address type='pci' domain='0x0000' bus='0x00' slot='*0x0c*' function='0x0'/> attach : ======== active=========== <mac address='0c:da:41:1e:02:9c'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> <mac address='0c:da:11:11:11:11'/> <address type='pci' domain='0x0000' bus='0x00' slot='*0x0d*' function='0x0'/> Device detached successfully detach : ========inactive=========== <mac address='0c:da:41:1e:02:9c'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> detach : ======== active=========== <mac address='0c:da:41:1e:02:9c'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> When execute the script for more than 1 times, You can see the pci slot of attached interface in live xml differs from the one in config xml. Is this intentional or a bug ? If not a bug, why?
