[RESOLVED] How do I use Q35 in virt-manager?
Pretty much what the title says. How do I use the Q35 chipset when creating a VM? I only have the i440x available in the drop-down menu. I assume I have to install it, however not sure how. I read something about qemu-kvm-ev but not sure what/were it is. Some articles seem a little convoluted so hoping someone can shed a little light for me. TIA.

Re: How do I use Q35 in virt-manager?
CentOS 7's libvirt/qemu do not supprt q35.
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.

Re: [RESOLVED] How do I use Q35 in virt-manager?
Is that a libvirt's limitation? qemu-kvm lists q35 for 7.
(I did just stumble on "Cannot live migrate between 6 and 8" -- no common machine strings.)

I think you may have installed the qemu-kvm-ev package produced by one of the SIGs. The CentOS base provided one on el7 does not support Q35:

Re: [RESOLVED] How do I use Q35 in virt-manager?
My bad. 
I had installed centos-release-openstack-ocata (for openstack CLI), which had pulled in centos-release-qemu-ev.
The qemu-kvm-ev from repo centos-qemu-ev then obsoleted qemu-kvm.
Yes, that is from CentOS Virtualization SIG.
