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
Hello,
I have configured a new ACS?

Yes. I just noticed it right now myself. I dumped xml for a centos 7 guest
on both installations and for the one that detects as /dev/vda, there is no
virtio-scsi controller type in it's xml. However for another running on new
ACS installation which detects disk as /dev/sda, there is "virtio-scsi"
controller type in it's xml. I even tested it's write speed using dd and it
is was awesome. I was worried wrongly :)
Thanks

Virtio scsi is detected as sdX. It's absolutely fine.

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

Hi,
:D I just noticed right now that I have pasted my question into subject
line instead of message body ;D
Both are version 4.12.0.0. A guest running CentOS 7.6 on old ACS detects
disk as vda but same guest on new one detects as sda. Templates on ACS
installation. OS type "CentOS 7" gives virtio access to CentOS 7.6 on old
ACS.

That's a nice email subject indeed :)
For template, make sure that you are using identical OS type for that
template, on the new ACS as on the old one. Are these ACS installations of
the same version?
Keep in mind that "CentOS 7" is not the same as "CentOS 7.2" from ACS
perspective and the last one will consume virtio, while the previous one
will spin IDE controller inside a VM...
