[one-users] Migration problem

Hello ,
I faced this scenario a few days back and this is due to the fact that there
are 2 versions of qemu that you have . The machine='pc' part will not
appear if you use the qemu that is installed in /usr/libexec/qemu-kvm
instead of the other one.
You can create a soft link as follows :
ls -l /usr/bin/kvm
lrwxrwxrwx 1 root root 21 Mar 22 00:44 /usr/bin/kvm -> /usr/libexec/qemu-kvm
Hope that helps.
Copy pasting from another thread:
By default,
libvirt will use rhel5.4.0 machine type, which is supported by
kvm-83-164.el5_5.12 but not supported by upstream qemu (you can see the
supported machine types in the log above).
So you have two options:
- either use /usr/libexec/qemu-kvm as the emulator
- or explicitly change machine type to something which is supported by
/usr/bin/qemu-system-x86_64 (e.g., pc-0.12) --- >* this supports your
"machine = pc" part.*
cheers

How can I change the machine type from the default of rhel5.4.0 to pc from
within the VM template?
if I add to the vm template:
OS = [ ARCH = "x86_64", MACHINE = "pc" ]
and even though onevm show reveals:
OS=[
ARCH=x86_64,
MACHINE=pc ]
deployment.0 still only shows:
<type arch='x86_64'>hvm</type>
as opposed to the expected:
<type arch='x86_64' machine='pc'>hvm</type>

Hi,
I have install opennebula vers. 2.0.1-1 with libvirt vers. 0.7.7
When I create a virtual machine, it's working fine but few minutes after,
libvirt crash.
If I don't run any virtual machine, libvrit has no problem.
If I start a machine manually using virsh:
- if opennebula is working: libvirt has the same problem.
- if opennebula is stop: libvirt has no problem
If seems that every 10 minutes, when opennebula try to monitor the virtual
machine, libvirt crash at the same moment.
In oned.log I have:

Sorry for the noise! It seems the problem is in xentop (for some reason
it reports wrong free memory capacity what doesn't correspond to the
'free -m' output.

Message-ID: <4D8C66D6.8000703 at gmail.com>
Content-Type: text/plain; charset=UTF-8; format=flowed
Dear all,
is it possible to change ONE VM template format in case of OpenVZ
hypervisor and would it be enough to take those changes into account in
OvzDriver.cc only? Or ONE VM template format is robust and the changes
in other files are required as well (if yes then in which files?)?
For example, I'd like to write MEMORY parameter for OpenVZ VM as
MEMORY = [ KMEMSIZE="14372700:14790164",
LOCKEDPAGES="2048:2048",
PRIVVMPAGES="65536:69632",
SHMPAGES="21504:21504",
PHYSPAGES="0:unlimited",
VMGUARPAGES="33792:unlimited",
OOMGUARPAGES="26112:unlimited" ]
whereas for xen now it looks like
MEMORY = 256.
Nikolay.
