VDI - SPICE zero clients
by cmcl＠dneg.com
Hi,
I gt hold of a 10zig V1200-P for testing VDI under ovirt/RHEV, as I'd read that they support SPICE. However, I haven't found how to connect it successfully to a VM as yet. Has anyone had any experience with these using ovirt/RHEV? I haven't been able to find any manuals or support info on the 10zig website regarding these V1200-P zero clients. I've read that they are discontinuing SPICE support in the future, but I just need to be able to demonstrate it working for now.
Thanks for any help,
Cam

Console issues in a distributed environment over NAT
by shailigum＠gmail.com
Hi all, i'm trying to deploy oVirt to manage multiple 'data centers' (really just very basic deployments of single hosts using local storage that are deployed in varying geographic locations), where each host/resource pool is (unfortunately) only accessible via NAT.
I've setup port-forwards for all functions, including SPICE/VNC, but am running into issues with the 'console' button in the GUI. When I initially added the host I added it using the NAT IP, however when trying to connect to console the console.vv file generated from the GUI references the local (private) IP of the host, instead of the NAT IP of the upstream firewall - so I have to manually open the file to change it to the NAT IP in order to connect to a VM's console.
This is a minor annoyance for me, but it does ultimately the tool will be used by others who are less comfortable with steps like these. Is there a way around this, to have the console.vv generate with the IP oVirt is using to connect to the host, instead of its discovered local IP?
Also if you can think of any other concerns I may encounter in a NAT deployment like this, please share! Thanks!

NFS Mount on EMC VNXe3200 / User - Group 36:36 / Permission issue
by jeanbaptiste.coupiac＠nfrance.com
Hello,
I try to mount an NFS Data share from a EMC VNXe3200 export. Unfortunately,
NFS share cannot be mount, there is permission error.
(Indeed, after the same issue on another NFS ISO repo, I've change exported
directory user/group to 36:36, and O-Virt NFS mount was great).
So, I think issue with my VNXe3200 is regarding UID / GID owner on VNXe3200
side. After webex with EMC support, change owner / permission on VNXe side
seems not possible / supported.
Can I mount the NFS share with some options to avoid vdsm:kvm mounting issue
? Can I force mount with root ?
Regards,
Jean-Baptiste COUPIAC

Hi,
I have just re-installed centOS 7 in 3 servers and have configured gluster

PXE LOCALBOOT issue
by Michael Deffenbaugh
Hey all,
Provisioning a host with Foreman 1.17.1/Katello 3.6. The host
kickstarts fine but when it goes to reboot, iPXE fails to load the local
disk when the Foreman local boot kickstart menu (
https://github.com/theforeman/community-templates/blob/develop/provisioni...,
line 4-10) sends the command "LOCALBOOT 0". It simply fails and says "No
more network devices. No bootable device."
Is this a bug in iPXE? Any input would be greatly appreciated!

This seems to be in the phase where we create a local vm for the engine. We
do this with plain virt-install, nothing fancy. Searching the net for
"unsupported configuration: CPU mode 'custom'" finds other relevant
reports, you might want to check them. You can see the command in
bootstrap_local_vm.yml .
Please check/share versions of relevant packages (libvirt*, qemu*, etc) and
relevant logs (libvirt).
Also updating the subject line and adding Simone.
Best regards,

Unable to start VM
by Alex K
Hi all,
I did a routine maintenance today (updating the hosts) to ovirt cluster
(4.2) and I have one VM that was complaining about an invalid snapshot.
After shutdown of VM the VM is not able to start again, giving the error:
VM Gitlab is down with error. Exit message: Bad volume specification

I see also the following error:
VDSM command CopyImageVDS failed: Image is not a legal chain:
(u'b6af2856-a164-484a-afe5-9836bbdd14e8',)
Seems as a corrupt VM disk?
The VM had 3 snapshots. I was able to delete one from GUI then am not able
to delete the other two as the task fails. Generally I am not allowed to
clone, export or do sth to the VM.
Have you encountered sth similar. Any advice?
Thanx,
Alex
