[Users] Lifecycle / upgradepath
by Sven Kieske
Hi Community,
Currently, there is no single document describing supported
(which means: working ) upgrade scenarios.
I think the project has matured enough, to have such an supported
upgradepath, which should be considered in the development of new
releases.
As far as I know, currently it is supported to upgrade
from x.y.z to x.y.z+1 and from x.y.z to x.y+1.z
but not from x.y-1.z to x.y+1.z directly.
maybe this should be put together in a wiki page at least.
also it would be cool to know how long a single "release"
would be supported.
In this context I would define a release as a version
bump from x.y.z to x.y+1.z or to x+1.y.z
a bump in z would be a bugfix release.
The question is, how long will we get bugfix releases
for a given version?
What are your thoughts?

[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
This is a multipart message in MIME format.

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 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?

Hi,
it's me again....
I started my oVirt 'project' as a proof of concept,.. but it happend as always, it became production
Now, I've to move the iSCSI Master data to the real iSCSI traget.
Is there any way to do this, and to become rid of the old Master Data?
Thank you for your help
