[Users] Nested virtualization with Opteron 2nd generation and oVirt 3.1 possible?
by Gianluca Cecchi
Hello,
I have 2 physical servers with Opteron 2nd gen cpu.
There is CentOS 6.3 installed and some VM already configured on them.
Their /proc/cpuinfo contains
...
model name : Dual-Core AMD Opteron(tm) Processor 8222
...
kvm_amd kernel module is loaded with its default enabled nested option
# systool -m kvm_amd -v
Module = "kvm_amd"
Attributes:
initstate = "live"
refcnt = "15"
srcversion = "43D8067144E7D8B0D53D46E"
Parameters:
nested = "1"
npt = "1"
...
I already configured a fedora 17 VM as a oVirt 3.1 Engine
I'm trying to configure another VM as oVirt 3.1 node with
ovirt-node-iso-2.5.5-0.1.fc17.iso
It seems I'm not able to configure so that ovirt install doesn't complain.
After some attempts, I tried this in my vm.xml for the cpu:
<cpu mode='custom' match='exact'>
<model fallback='allow'>athlon</model>
<vendor>AMD</vendor>
<feature policy='require' name='pni'/>
<feature policy='require' name='rdtscp'/>
<feature policy='force' name='svm'/>
<feature policy='require' name='clflush'/>
<feature policy='require' name='syscall'/>
<feature policy='require' name='lm'/>
<feature policy='require' name='cr8legacy'/>
<feature policy='require' name='ht'/>
<feature policy='require' name='lahf_lm'/>
<feature policy='require' name='fxsr_opt'/>
<feature policy='require' name='cx16'/>
<feature policy='require' name='extapic'/>
<feature policy='require' name='mca'/>
<feature policy='require' name='cmp_legacy'/>
</cpu>
Inside node /proc/cpuinfo becomes
processor : 3
vendor_id : AuthenticAMD
cpu family : 6
model : 2
model name : QEMU Virtual CPU version 0.12.1
stepping : 3
microcode : 0x1000065
cpu MHz : 3013.706
cache size : 512 KB
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat
pse36 clflush mmx fxsr sse sse2 syscall mmxext fxsr_opt lm nopl pni
cx16 hypervisor lahf_lm cmp_legacy cr8_legacy
bogomips : 6027.41
TLB size : 1024 4K pages
clflush size : 64
cache_alignment : 64
address sizes : 40 bits physical, 48 bits virtual
power management:
2 questions:
1) Is there any combination in xml file to give to my VM so that oVirt
doesn't complain about missing hardware virtualization with this
processor?
2) suppose 1) is not possible in my case and I still want to test the
interface and try some config operations to see for example the
differences with RHEV 3.0, how can I do?
At the moment this complaint about hw virtualization prevents me to
activate the node.
I get
Installing Host f17ovn01. Step: RHEV_INSTALL.
Host f17ovn01 was successfully approved.
Host f17ovn01 running without virtualization hardware acceleration
Detected new Host f17ovn01. Host state was set to Non Operational.
Host f17ovn01 moved to Non-Operational state.
Host f17ovn01 moved to Non-Operational state as host does not meet the
cluster's minimum CPU level. Missing CPU features : CpuFlags
Can I lower the requirements to be able to operate without hw
virtualization in 3.1?
Thanks in advance,
Gianluca

Need VM run once api
by Chandrahasa S

Content-Type: text/plain; charset="US-ASCII"
Hi Experts,
We are integrating ovirt with our internal cloud.
Here we installed cloudinit in vm and then converted vm to template. We
deploy template with initial run parameter Hostname, IP Address, Gateway
and DNS.
but when we power ON initial, run parameter is not getting pushed to
inside the vm. But its working when we power on VM using run once option
on Ovirt portal.
I believe we need to power ON vm using run once API, but we are not able
get this API.
Can some one help on this.
I got reply on this query last time but unfortunately mail got deleted.
Thanks & Regards
Chandrahasa S

I need to import a kvm virtual machine from a standalone kvm into my ovirt =
cluster. Standalone is using local storage, and my ovirt cluster is using =
iscsi. Can i please have some advice on whats the best way to get this sys=
tem into ovirt?
Right now i see it as copying the .img file to somewhere=85 but i have no i=
dea where to start. I found this directory on one of my ovirt nodes:
/rhev/data-center/mnt/blockSD/fe633237-14b2-4f8b-aedd-bbf753bcafaf/master/v=
ms
But inside is just directories that appear to have uuid-type of names, and =
i can't tell what belongs to which vm.
Any advice would be greatly appreciated.
Thanks,
jonathan

oVirt nVidia vGPU driver questions
by femi adegoke
I'm on oVirt 4.2.6.
1) If I have a Tesla P4 (Pascal) GPU (non-GRID), do I use nVidia vGPU driver for RHEL KVM 6.2 or the Linux KVM vGPU 6.2 driver?
2) If I have a Grid K1 or K2, I assume the correct driver would be GRID 4.7?
3) Must the vGPU driver be installed on the host & in the vm?
4) Must the vGPU driver be installed first before I can run "yum -y install vdsm-hook-vfio-mdev”

oVirt Node 4.3 Master on fc28
by femi adegoke
4.3 Master is looking good!!
A few questions:
- In Step #2: Fqdns: for a 3 host cluster, are we to add the 2nd & 3rd
hosts?
- In Step #5: Bricks:
What effect does the RAID setting have?
Enable Dedupe & Compression is new?
Configure LV Cache: what do we enter for SSD? What happens if my disks
are already all SSD, do I still benefit from using this?

Re: huge page in ovirt 4.2.7
by Sharon Gratch
Hi Fabrice,
The "hugepages" custom property value in oVirt should be set to *size of
the pages in KiB* (i.e. 1GiB = 1048576, 2MiB = 2048).
In addition, it is recommended to set the huge page size of the VM to the
largest size supported by the host.
In the configuration you sent, the huge page size of the VM is set to 64
KiB and since the VM's allocated memory size is at least 32,768 MiB then it
requires at least (32768 * 1024/64=) 524,288 pages. Since you only have 120
pages declared in the host then it failed with an error "...there are not
enough free huge pages to run the VM".
So to solve the problem, please change the VM's huge page size to be the
same as the host's huge page supported size which is 1GiB and therefore
hugepages value should be 1048576 KiB instead of 64:
<custom_property>
<name>hugepages</name>
<value>*1048576*</value>
</custom_property>
Please note that since total VM's memory size is no more than 64 GB then
only 64 pages will be needed by the VM and it's < 120 pages supported by
the host and therefore OK.
Hope it helped.
Regards,
Sharon
