Re: [ovirt-users] vm freezes when using yum update

------=_Part_1782636_158770879.1499670432485 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Hi Yanis, I just wanted to share something with you regarding the issue I am facing. Basically, I found out If during creating a new VM I choose IDE for disk in= terface instead of VirtIO everything will work perfectly without any issue. Regarding your suggestion to switch to CentOS kernel, Unfortunately, we are= not able to do it because of the fact that we can not effort to have downt= ime for existing running VMs. With Best RegardsM.Mahboubian On Monday, July 3, 2017, 4:49 PM, Yaniv Kaul <ykaul(a)redhat.com&gt; wrote: On Mon, Jul 3, 2017 at 11:00 AM, M Mahboubian <m_mahboubian(a)yahoo.com&gt; wrot= e: Hi Yanis, Thank you for your reply.=C2=A0 | Interesting - what interface are they using?| Is that raw or raw sparse? = How did you perform the conversion?
