[libvirt-users] vlan and libvirt
by Vidon Guillaume
Hi,
I have to deploy some Ubuntu machines via pxe/dhcp/tftp/preseed/puppet on a
vlan. the switches are configured to add vlan tag to the traffic to/from those
machines. To test new configuration, i tried to configure a domain alike it was
connected by a port of a managed switch configured in general mode where untag
id is not 1. Anybody have already done this ? Can i use openvswitch to do this ?
Thank you

[libvirt-users] RAID1 over IP?
by David Ehle
I asksed about this in November last year but got on response. Anyone
have any ideas now?
Does anyone here have any experience with using KVM/libvirt with RAID1
over IP/DRBD or other HA solution?
I'm trying to figure out the hardware configuration I would need to be
able to survive a failure or planned shutdown of any one unit in a
virtualization cluster.
KVM/libvirt makes moving running VM's from one host to another a no
brainer, but I'm trying to figure out the right way to be able to take a
the storage backend for maintenance without disrupting the VMs.
Right now I'm thinking something like KVM + libvirt + heartbeat/corosync +
pacemaker + DBRM on Ubuntu 10.04 with 3 or 4 nodes - 2 hosts, 2 storage,
or 1 host, 1 host + storage, 1 storage.
Any thoughts?
Thanks!

[libvirt-users] Char dev error
by Jatin Kumar
Hello,
I have been trying to migrate a guest from one host to another.
But it is showing this error:
virsh --connect qemu+ssh://root@host1/system migrate --live
--undefinesource testvm3 qemu+ssh://root@host2/system
tcp://host2:48160
error: operation failed: failed to retrieve chardev info in qemu with
'info chardev'
I have tried this command from the host1 also but it shows the same error.
Another thing i would like to ask is the that whats the use of
migrateuri in migrate command ?
