Hello
trying to migrate a VM from one host to another, a big VM with 96GB of RAM,
I found that when the migration completes, the VM goes to a paused satte
and cannot be resumed. The libvirt/qemu log it gives is this:
2016-09-28T12:18:15.679176Z qemu-kvm: error while loading state section id

If you're running a guest on an Intel machine without unrestricted mode
support, the failure can be most likely due to the guest entering an invalid
state for Intel VT. For example, the guest maybe running in big real mode
which is not supported on less recent Intel processors.

Searching for errors like this I found some bug report about kernel issues
but I don't think it's the case, other VMs spawned from the same image
migrate without any issue. I have toi say that the original host running
the VM has some RAM problem (ECC multibit fault in one DIMM). Maybe that's
the problem?
How can I properly read this error log?
Thanks

KVM: entry failed, hardware error 0x80000021
If you're running a guest on an Intel machine without unrestricted mode
support, the failure can be most likely due to the guest entering an invalid
state for Intel VT. For example, the guest maybe running in big real mode
which is not supported on less recent Intel processors.

Searching for errors like this I found some bug report about kernel issues
but I don't think it's the case, other VMs spawned from the same image
migrate without any issue. I have toi say that the original host running the
VM has some RAM problem (ECC multibit fault in one DIMM). Maybe that's the
problem?
that seems quite likely. If you run the same VM on a different host and try to migrate
it, does it work?
How can I properly read this error log?
Thanks

Hello
Today I've the faulty DIMMs replaced, started the same VM again and did the
same migration and this time worked, so it was 100% due to that.
The problem that make me wonder a bit is: if it's the source host with
memory problem the one which blocks the correct migration, a faulty DIMM
will force you to stop the VMs running on that host, because you cannot
simply migrate them away to do the maintenence tasks...

that seems quite likely. If you run the same VM on a different host and
try to migrate
it, does it work?

Today I've the faulty DIMMs replaced, started the same VM again and =

The problem that make me wonder a bit is: if it's the source host with =

Ok, what I said is not true :( I didn't try to migrate again to the same
host that gave the initial problem, and the problem is still there. The
destination host has no HW problem (at least nothing that the system
reports, maybe I should try with an extensive memtest86) and the source
problem now has no memory issues neither. So, my question is now: how can I
debug this problem? The only difference that this host (vmhost01) has is
that it was the first host installed in my self-hosted engine installation.
But I have already reinstalled it from GUI and menawhile I've upgraded to
4.0.4 from 4.0.3.
Any idea?

Hello
Today I've the faulty DIMMs replaced, started the same VM again and did
the same migration and this time worked, so it was 100% due to that.
The problem that make me wonder a bit is: if it's the source host with
memory problem the one which blocks the correct migration, a faulty DIMM
will force you to stop the VMs running on that host, because you cannot
simply migrate them away to do the maintenence tasks...

from 4.0.3.
does it happen only for the big 96GB VM? The others which you said are =
working, are they all small?
Might be worth trying other system stability tests, playing with =
safer/slower settings in BIOS, use lower CPU cluster, etc
=20
Any idea?

Hello
=20
Today I've the faulty DIMMs replaced, started the same VM again and =
did the
same migration and this time worked, so it was 100% due to that.
=20
The problem that make me wonder a bit is: if it's the source host with =
memory
problem the one which blocks the correct migration, a faulty DIMM =
will force you to stop the VMs running on that host, because you cannot =
simply migrate them away to do the maintenence tasks...

that is a very low level error really pointing at HW issues. It may or may
not be detected by memtest…but I would give it a try
I left memtest86 running for 2 days and no error detected :(
The only difference that this host (vmhost01) has is that it was the
first
host installed in my self-hosted engine installation. But I have already
reinstalled it from GUI and menawhile I've upgraded to 4.0.4 from 4.0.3.
does it happen only for the big 96GB VM? The others which you said are
working, are they all small?
Might be worth trying other system stability tests, playing with
safer/slower settings in BIOS, use lower CPU cluster, etc
Yep, it happens only for the 96GB VM. Other VMs with fewer RAM (16GB for
example) can be created on or migrated to that host flawlessly. I'll try to
play a little with BIOS settings but otherwise I'll have the HW replaced. I
was only trying to rule out possible oVirt SW problems due to that host
being the first I deployed (from CLI) when I installed the cluster.
Thanks!

Hello
just for the record, after I have that server replaced (only
motherboard+ram+controller, same disks), now everything works ok, so it was
definitely an hardware issue.
Thanks everyone for the troubleshoot help!
