[ovirt-users] Ovirt on GCP
Dear sirs, I installed an ovirt4.5 platform on Google Cloud (2x N1 VMs / Centos stream8: 1 engine, 1 node / Nested virtualization enabled). While it works well and I could import an existing VM from our onpremiss oivrt site, I m just facing to a fundemental problem: How to assign an IP address to Level2 VM ? I tried to assign a static IP usually reserved for a GCP L1 VM in vain; it cannot comunicate with outside. If anyone could give me any advise, I would be happy. Thanks in advance.

Re: [Users] Destktop VM to Server VM ?
Thanks a lot Itamar. Everything became clear. Unfortunately, We are still using ovirt 3.0, for which I think ovirt-shell is not available. So, I will make a small java program.

Re: [Users] Destktop VM to Server VM ?
Thaks a lot for your suggestion. in fact I found the parameter which specifies server/desktop, checking the output of VMs' parameters by REST (/api/vms). Is it this very "type" paramter to change? Best RGDS Hideo GOTO P.S. I would be happy if you could recomend me any tool, if existing, which might make it easy to update parameters by REST. 2013/1/4 Itamar Heim : > On 01/03/2013 05:32 PM, Hideo Goto wrote: >> >> First of all, a Happy new year to every subscriber of the list. >> >> My first concern of the year about ovirt: >> >> Is it possible to change the type of an existing VM from desktop to >> server by any possible means? >> In my case, the VM was imported from KVM to Ovirt 3.0 environment >> using virt-v2v.

[Users] Destktop VM to Server VM ?
First of all, a Happy new year to every subscriber of the list. My first concern of the year about ovirt: Is it possible to change the type of an existing VM from desktop to server by any possible means? In my case, the VM was imported from KVM to Ovirt 3.0 environment using virt-v2v. I have just found out that the VM was recognized as desktop while expected as server . Thanks in advance for any advise. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [Users] Ovirt does'nt recognize "Quad-core AMD Opteron" as Opteron
Dear friends, Indeed, your suggestion about NX bit solved our problem. NX bit option on our Proliant server was disabled for god-knows-what-reason. Once the NX bit function is enabled, the processor is now recognized as "Opteron G3", and the 2 HP server nodes were succesfully integrated to a existing production cluster today thanks to all of you. Just FYI, output of "virsh -r capabilities" were giving "Athlon" as CPU model, when NX was disabled. Most of Proliant servers has BIOS switches for NX bit function: "No-Execute Page Protection" for AMD models and "Non-Execute Memory Protection" for Xeon models. HP tells that the these options are enabled by factory default. So, those who get trapped by this mistake as me, should be really minority. Sorry for distubing all of you by such a stupid mistake, and thanks again to all of you. Very best regards.

Re: [Users] Ovirt does'nt recognize "Quad-core AMD Opteron" as Opteron
Dear Yaniv Kaul, Thanks for your propmt anwer. It seems that your patience did not allow your reading to continue after "CPU_TYPE_INCOMPATIBLE_WITH_CLUSTER". As reported in the last part of my previous mail, the output from vdsClient shows us that the processor is recognised as none of AMD Opteron G1, G2 or G3 (cpuFlags=...) . Thus, Quad-core AMD 2384 cannot match any of Ovirt CPU type options. For confriming, I have just tried, upon reciept of your reply, to add the host to cluster of other CPU types (G1, G2 ..) , to get the same unfortunate result.
