Hello,
I am having an issue with libvirt in my Nimbus cloud setup. When I use the
Nimbus VM creation test scripts on a VMM node (using libvirt), the VM is
created without a problem. However, when I attempt to create a new VM using
Nimbus (which then tries to create the VM on the VMM node), I encounter the
following error:
---------------------------------------------------------------------------------------------------------------------------------------------
$ ./nimbus-cloud-client-022/bin/cloud-client.sh --run --name testimage

I checked /var/log/libvirtd.log, and found the following:
---------------------------------------------------------------------------------------------------------------------------------------------
2014-01-31 20:48:39.311+0000: 2888: info : libvirt version: 0.9.8

of file while reading data: Input/output error
---------------------------------------------------------------------------------------------------------------------------------------------
I don't know if this is relevant, but I also noticed this warning when
creating the VM through the test scripts mentioned above:
---------------------------------------------------------------------------------------------------------------------------------------------
2014-01-31 05:41:44.018+0000: 1351: warning : qemuDomainObjTaint:1134 :

is tainted: high-privileges
---------------------------------------------------------------------------------------------------------------------------------------------
I assumed this was a permissions issue, but I double checked and everything
seems in order. I did not have this issue on my previous Nimbus cloud setup.
Thanks,
Josh
