Hi Yaniv,
Thanks for your reply. Apologies for my late reply we had a long holiday he=
re.=C2=A0
To answer you:
Yes the =C2=A0guest VM become completely frozen and non responsive as soon =
as its disk has any activity for example when we shutdown or do a yum updat=
e.=C2=A0
Versions of all the components involved - guest OS, host OS (qemu-kvm versi=
on), how do you run the VM (vdsm log would be helpful here), exact storage =
specification (1Gb or 10Gb link? What is the NFS version? What is it hosted=
on? etc.)=C2=A0Y.
Some facts about our environment:
1) Previously, this environment was using XEN using raw disk and we change =
it to Ovirt (Ovirt were able to read the VMs's disks without any conversion=
.)=C2=A02) The issue we are facing is not happening for any of the existing=
VMs.=C2=A03) This issue only happens for new VMs.4) Guest (kernel v3.10) a=
nd host(kernel v4.1) OSes are both CentOS 7 minimal installation.=C2=A05) N=
FS version 4 and Using Ovirt 4.16)=C2=A0The network speed is 1 GB.7)=C2=A0T=

a SAN device which is connected to the NFS server using fiber channel.
So for example during shutdown also it froze and shows something like this =
in event section:
VM ILMU_WEB has been paused due to storage I/O problem.

Dear all,I appreciate if anybody could possibly help with the issue I am fa=
cing.
In our environment we have 2 hosts 1 NFS server and 1 ovirt engine server. =
The NFS server provides storage to the VMs in the hosts.
I can create new VMs and install os but once i do something like yum update=
the VM freezes. I can reproduce this every single time I do yum update.
Is it paused, or completely frozen?=C2=A0
what information/log files should I provide you to trubleshoot this?
Versions of all the components involved - guest OS, host OS (qemu-kvm versi=

specification (1Gb or 10Gb link? What is the NFS version? What is it hosted=

=C2=A0Regards

New subject: vm freezes when using yum update
On Mon, Jul 3, 2017 at 6:49 AM, M Mahboubian <m_mahboubian(a)yahoo.com> wrote:
Hi Yaniv,
Thanks for your reply. Apologies for my late reply we had a long holiday
here.
To answer you:
Yes the guest VM become completely frozen and non responsive as soon as
its disk has any activity for example when we shutdown or do a yum update.
Versions of all the components involved - guest OS, host OS (qemu-kvm
version), how do you run the VM (vdsm log would be helpful here), exact
storage specification (1Gb or 10Gb link? What is the NFS version? What is
it hosted on? etc.)
Y.
Some facts about our environment:
1) Previously, this environment was using XEN using raw disk and we change
it to Ovirt (Ovirt were able to read the VMs's disks without any
conversion.)
Interesting - what interface are they using?
Is that raw or raw sparse? How did you perform the conversion? (or no
conversion - just copied the disks over?)
2) The issue we are facing is not happening for any of the existing
VMs.
*3) This issue only happens for new VMs.*
New VMs from blank, or from a template (as a snapshot over the previous
VMs) ?
4) Guest (kernel v3.10) and host(kernel v4.1) OSes are both CentOS 7
minimal installation.
Kernel 4.1? From where?
*5) NFS version 4* and Using Ovirt 4.1
6) *The network speed is 1 GB.*
That might be very slow (but should not cause such an issue, unless
severely overloaded.
7) The output for rpm -qa | grep qemu-kvm shows:
* qemu-kvm-common-ev-2.6.0-28.e17_3.6.1.x86_64*
* qemu-kvm-tools-ev-2.6.0-28.e17_3.6.1.x86_64*
* qemu-kvm-ev-2.6.0-28.e17_3.6.1.x86_64*
That's good - that's almost the latest-greatest.
*8) *The storage is from a SAN device which is connected to the NFS
server using fiber channel.
So for example during shutdown also it froze and shows something like this
in event section:
*VM ILMU_WEB has been paused due to storage I/O problem.*
We might need to get libvirt debug logs (and perhaps journal output of the
host).
Y.

Dear all,
I appreciate if anybody could possibly help with the issue I am facing.
In our environment we have 2 hosts 1 NFS server and 1 ovirt engine server.
The NFS server provides storage to the VMs in the hosts.
I can create new VMs and install os but once i do something like yum
update the VM freezes. I can reproduce this every single time I do yum
update.
Is it paused, or completely frozen?
what information/log files should I provide you to trubleshoot this?
Versions of all the components involved - guest OS, host OS (qemu-kvm
version), how do you run the VM (vdsm log would be helpful here), exact
storage specification (1Gb or 10Gb link? What is the NFS version? What is
it hosted on? etc.)
Y.

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? (or no conversion - just copied the dis=
ks over?)
The VM disks are in the SAN storage in order to use oVirt we just pointed t=
hem to the oVirt VMs. This is how we did it precisely:First we created the =
VMs in oVirt with disks which are the same size as the existing disks. then=
we deleted these disks which was generated by oVirt and renamed our existi=
ng disks to match the deleted ones naming-wise. Finally we started the oVir=
t VMs and they were able to run and these VMs are always ok without any iss=
ue.
The new VMs which have problem are from scratch (no template). One thing th=
ough, all these new VMs are created based on an CentOS 7 ISO. We have not t=
ried any other flavor of Linux.
The kernel 4.1 is actually from Oracle Linux repository since we needed to =
have OCFS2 support. So after installing oVirt we updated the kernel to Orac=
le Linux kernel 4.1 since that kernel supports OCFS2.
| We might need to get libvirt debug logs (and perhaps journal output of th=
e host).
I'll get this information and post here.

Hi Yaniv,

To answer you:
Yes the =C2=A0guest VM become completely frozen and non responsive as soon =

Versions of all the components involved - guest OS, host OS (qemu-kvm versi=

Some facts about our environment:
1) Previously, this environment was using XEN using raw disk and we change =
it to Ovirt (Ovirt were able to read the VMs's disks without any conversion=
.)=C2=A0
Interesting - what interface are they using?Is that raw or raw sparse? How =
did you perform the conversion? (or no conversion - just copied the disks o=
ver?)=C2=A0
2) The issue we are facing is not happening for any of the existing VMs.=C2=
=A03) This issue only happens for new VMs.
New VMs from blank, or from a template (as a snapshot over the previous VMs=
) ?=C2=A0
4) Guest (kernel v3.10) and host(kernel v4.1) OSes are both CentOS 7 minima=
l installation.=C2=A0
Kernel 4.1? From where?=C2=A0
5) NFS version 4 and Using Ovirt 4.16)=C2=A0The network speed is 1 GB.
That might be very slow (but should not cause such an issue, unless severel=

7)=C2=A0The output for rpm -qa | grep qemu-kvm shows:=C2=A0 =C2=A0 =C2=A0qe=

That's good - that's almost the latest-greatest.=C2=A0
8)=C2=A0The storage is from a SAN device which is connected to the NFS serv=

So for example during shutdown also it froze and shows something like this =

VM ILMU_WEB has been paused due to storage I/O problem.

New subject: vm freezes when using yum update

The VM disks are in the SAN storage in order to use oVirt we just pointed
them to the oVirt VMs. This is how we did it precisely:
First we created the VMs in oVirt with disks which are the same size as
the existing disks. then we deleted these disks which was generated by
oVirt and renamed our existing disks to match the deleted ones naming-wise.
Finally we started the oVirt VMs and they were able to run and these VMs
are always ok without any issue.
The new VMs which have problem are from scratch (no template). One thing
though, all these new VMs are created based on an CentOS 7 ISO. We have not
tried any other flavor of Linux.
The kernel 4.1 is actually from Oracle Linux repository since we needed to
have OCFS2 support. So after installing oVirt we updated the kernel to
Oracle Linux kernel 4.1 since that kernel supports OCFS2.
Would it be possible to test with the regular CentOS kernel? Just to ensure
it's not the kernel causing this?
Y.

I'll get this information and post here.

To answer you:
Yes the guest VM become completely frozen and non responsive as soon as
its disk has any activity for example when we shutdown or do a yum update.
Versions of all the components involved - guest OS, host OS (qemu-kvm
version), how do you run the VM (vdsm log would be helpful here), exact
storage specification (1Gb or 10Gb link? What is the NFS version? What is
it hosted on? etc.)
Y.
Some facts about our environment:
1) Previously, this environment was using XEN using raw disk and we change
it to Ovirt (Ovirt were able to read the VMs's disks without any
conversion.)
Interesting - what interface are they using?
Is that raw or raw sparse? How did you perform the conversion? (or no
conversion - just copied the disks over?)
2) The issue we are facing is not happening for any of the existing VMs.
*3) This issue only happens for new VMs.*
New VMs from blank, or from a template (as a snapshot over the previous
VMs) ?
4) Guest (kernel v3.10) and host(kernel v4.1) OSes are both CentOS 7
minimal installation.
Kernel 4.1? From where?
*5) NFS version 4* and Using Ovirt 4.1
6) *The network speed is 1 GB.*
That might be very slow (but should not cause such an issue, unless
severely overloaded.
7) The output for rpm -qa | grep qemu-kvm shows:
* qemu-kvm-common-ev-2.6.0-28. e17_3.6.1.x86_64*
* qemu-kvm-tools-ev-2.6.0-28. e17_3.6.1.x86_64*
* qemu-kvm-ev-2.6.0-28.e17_3.6. 1.x86_64*
That's good - that's almost the latest-greatest.
*8) *The storage is from a SAN device which is connected to the NFS
server using fiber channel.
So for example during shutdown also it froze and shows something like this
in event section:
*VM ILMU_WEB has been paused due to storage I/O problem.*
We might need to get libvirt debug logs (and perhaps journal output of the
host).

Dear all,
I appreciate if anybody could possibly help with the issue I am facing.
In our environment we have 2 hosts 1 NFS server and 1 ovirt engine server.
The NFS server provides storage to the VMs in the hosts.
I can create new VMs and install os but once i do something like yum
update the VM freezes. I can reproduce this every single time I do yum
update.
Is it paused, or completely frozen?
what information/log files should I provide you to trubleshoot this?
Versions of all the components involved - guest OS, host OS (qemu-kvm
version), how do you run the VM (vdsm log would be helpful here), exact

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

Dear all,I appreciate if anybody could possibly help with the issue I am fa=
cing.
In our environment we have 2 hosts 1 NFS server and 1 ovirt engine server. =
The NFS server provides storage to the VMs in the hosts.
I can create new VMs and install os but once i do something like yum update=
the VM freezes. I can reproduce this every single time I do yum update.
Is it paused, or completely frozen?=C2=A0
what information/log files should I provide you to trubleshoot this?
Versions of all the components involved - guest OS, host OS (qemu-kvm versi=
on), how do you run the VM (vdsm log would be helpful here), exact storage =
specification (1Gb or 10Gb link? What is the NFS version? What is it hosted=
on? etc.)=C2=A0Y.
=C2=A0Regards
