Subject Re: VirtIO not detected by guest on new ACS with new KVM host. I have moved a CentOS 7 template from another ACS to new one. The guests deployed from same template on old ACS detects disk devices as vda but a guest deployed from same template on new ACS detects disks as sda. To move the template I went to old ACS and requested download link for template. Then registered it on new one and selected VirtIO-SCSI as well. Why VirtIO is not enabled for guests on new ACS

Kindly double check if both OS type and the controller defined are
identical - it makes no sense to me to use same settings but get different
results.

Also, try CentOS 7.2 on the new installation (though, explicitly settings
the controller on the template should override whatever controller is
defined IN the OS Type).

Can you do the "lspci" inside the OS/VM, to show the controller? Or
actually "virsh dumpxml i-x-y-VM" would be good as well (grepping the
controller...)

Best,
Andrija
