Re: [Users] Virtual Disk creation - really slow (config issue?) e.g 20GB disk created in 23 mins - NFS server/Gigabit switch - can anyone suggest why speed is so slow ? (at this rate it would take 1hr 40 mins to create a 100GB disk...)

Thank you Gary. After re-mounting the NFS share with async it dramatically increased the speed ! I can now create a 10GB virtual disk in 2 mins (rather than 10 mins) Is using the async option more likely to cause data corruption though ?

[Users] console confusion
by Joe Pruett 25 Mar '12

25 Mar '12

my desktop system is running centos6 with downloaded firefox 10. i downloaded and compiled spice-xpi 2.7. i can interact with the console one time, then i have to log out of the portal and back in again in order to get the icon and popup menu to not be greyed out anymore. so i have a few questions: 1. is this just an issue of using an unsupported browser? 2. ie9 seems to be supported, but i obviously need something more to be able to view the console. i don't get an error, so i'm not sure what i should install. the spice viewer i find at spice-space needs libraries and the libraries there are just a zip file. does something need to go on the server to auto-download code? 3. i figured i'd try vnc, but in that case the icon and menu option are always greyed out. just trying vnc to the appropriate host requires a password and none of the ones i'd suspect seem to work. is there a default? or some way to find the password? 4. i saw some vague discussion of display networks in the manual, but nothing in the interface seems to jump out at me. it seems like for most uses, a simple web based console is what is needed. java or active-x (or javascript/canvas magic). is this something that is in the commercial version, but not the free one? 5. or am i just missing something painfully obvious?

[Users] Outage Update - www.ovirt.org and gerrit.ovirt.org
by Ofer Schreiber 25 Mar '12

25 Mar '12

www.ovirt.org and gerrit.ovirt.org are now up and running. We experienced two issues: 1. DB corruption on www.ovirt.org, caused by a full file system. 2. Faulty gerrit service, probably caused by #1. Both issues were handled by oVirt infra team (mburns, quaid and myself) Thank you for your patience. Ofer Schreiber oVirt infra team

[Users] Passing a hint/message to a VM when it boots
by Kyrre Begnum 25 Mar '12

25 Mar '12

Hello, when creating a new VM from a template, i'd like to pass a hint of some sort ( perhaps a hostname ) to it so that the internal config managment system can do the rest of the setup. This should also be programmable via the REST API, as I want to use it for automated deployments. Has anyone had success doing this with Ovirt? i can only see two approaches: - Put the hint in a floppy / iso and mount it on the VM. - Hardcode a MAC address and let a DHCP server provide the hostname Both of these do not seem very optimal to me. I'd appreciate some thoughts from the community on how to proceed. Thanks in advance, k

[Users] Problems removing a VM
by Andre Kostur 23 Mar '12

23 Mar '12

I'm having some problems trying to remove a VM. If I attempt to remove it, all the UI tells me is that it failed. No indications as to why it failed. However, if I dig into the logs on the server, it seems to be complaining that it cannot find the volume ("Failed to DeleteImageGroupVDS, error = Volume does not exist:"). If I attempt to just remove the disk from the VM, I get the same sort of response. The storage domain claims that it is active. What's next? (I only have 1 storage domain, 1 host, 1 cluster (OK, technically 2 if you count "default"), 1 datacenter) -- *Andre Kostur*
