Subject [URGENT - HELP NEEDED]
Date Sun, 15 Mar 2015 16:19:07 GMT
Hi guys,

we have updated the cloudstack from 4.3.0 to 4.3.2 (OS updated right before
that, from CentOS 6.5 to CentOS 6.6)

And now I can not start SYSTEM VR - that is used for SHARED GUEST network
anymore.
And some VMs are down - and cant be started because they depend on this
VR...

VPC VRs are created fine, so new VR for VPC are created fine, but this one
fro Guest network fails to start:

Here you can see, after agent copies template from secondary storage, to
primary local storage, it created base image, and backing file - so storage
setup seems completed.

Than all out of sudden we have errors:

can't find connection: KVM, for vm: r-2281-VM, continue
2015-03-15 16:52:45,677 DEBUG [kvm.resource.LibvirtConnection]
(agentRequest-Handler-3:null) can't find connection: LXC, for vm:
r-2281-VM, continue
2015-03-15 16:52:45,677 DEBUG [kvm.resource.LibvirtConnection]
(agentRequest-Handler-3:null) can't find which hypervisor the vm used ,
then use the default hypervisor
2015-03-15 16:52:45,678 DEBUG [kvm.resource.LibvirtComputingResource]
(agentRequest-Handler-3:null) Failed to get dom xml:
org.libvirt.LibvirtException: Domain not found: no domain with matching
name 'r-2281-VM'

 - and BTW - absolutely NOTHING in the libvirt log !


Here is the full log, with all the steps, on the host that doesnt host any
other VMs (except one - so log is easy to read) - you can notice after 1st
fail, agent copies new image/backing file, and tries again with new image...

And BTW, same template is of course used for both System VR and VPC VRs...
