[libvirt-users] Backups failing due to snapshot already exists
by Phill Edwards
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
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.

[libvirt-users] Problem in bridged networking
by Aditya Gupta
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. I am able to connect to
this virtual machine by another computer on same network.
The virtual machine is hosting a simple python http server on port 8000,
while some other service is running on port 80
When I try his on my main server :
# curl 10.1.3.31:80
Response I get is this :
* Rebuilt URL to: 10.1.3.31:80/
* Hostname was NOT found in DNS cache
* Trying 10.1.3.31...
* Connected to 10.1.3.31 (10.1.3.31) port 80 (#0)

> Host: 10.1.3.31
> Accept: */*
>
* Recv failure: Connection reset by peer
* Closing connection 0
curl: (56) Recv failure: Connection reset by peer
But when I try this on any other port
# curl 10.1.3.31:8000
Response I get is this:
* Rebuilt URL to: 10.1.3.31:8000/
* Hostname was NOT found in DNS cache
* Trying 10.1.3.31...
* connect to 10.1.3.31 port 8000 failed: Connection timed out

[libvirt-users] virsh channel
by Tadas
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
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

[libvirt-users] problem with dnsmasq and dhclient
by Patrick Pichon
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

[libvirt-users] Windows guest and virtio serial port
by Tadas
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:
