I mounted this with the command: mount /dev/HostVG/Data /data And now I have a /data/images directory (as well as /data/core).

[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
Hi. After my many issues with spice I have finally sorted them out. Now I am having an issue with the speed of virtual disk creation - when I go to create a virtual disk it takes a long time (far to long to be usable) My setup is as following 3 servers:- 1 Frontend (ovirt engine) - Fedora 16- external + local IP (91.215.xxx.xx + 10.0.0.10) 1 Ovirt node (using the node .iso) - external + local IP (ovirtmgmt (eth0) - 91.215.xxx.xxx and LAN (eth1) - 10.0.0.101) 1 NFS storage - external + local IP - I attached the storage using the Local IP (10.0.0.190) All servers are connected via a Gigabit switch (so speed should be better) I can scp between servers far faster - I'm almost sure its due to the node ovirtmgmt address being an external (internet ip) and not LAN ip. - therefore the traffic is not just going over the gigabit switch but via the core router in the DC... Can anyone suggest how I can 'debug' where the slowness is coming from On my NFS server I have it setup like (in /etc/exports) /storage1 *(rw,sync,no_subtree_check) I had previous tried setting up the node on a LAN IP previously and it caused spice to not work - as the node had no internet access / DNS - I also tried making the frontend server a gateway (and using - iptables -t nat -A POSTROUTING -j MASQUERADE ) - this also cause spice to not work (as it always tried to connect to the 10.0.0.x address from my desktop - and fail..)

[Users] rename the storage by error
Hi everyone, I got an issue with the storage on my Ovirt lab. I have a Ovirt manager (fedora16) and a host (ovirt node 2.2.3) on a HP server, my storage called "vmstore" was created with good rights "vsdm:kvm" on my ovirt manager's local drive. But i made an error, ovirt was running and i've rename with "mv" command the "uid folder" inside "vmstore" folder to an other folder called temp, i've delete the vmstore folder, re create it, and move the "uid folder" to the "vmstore" folder re created with good rights. Now i've got a inactive storage, impossible to change anything, i can create new storage but i can't activate it. Is anyone got an idea? i can do anything esle on my ovirt lab.

You can drop to the shell using F2 and create the directory that way. IMO, since we restrict the location you can create a local data store, we should automatically create that when configuring the local datastore. We can't actually pre-create the directory since it's a mounted filesystem, but it might be possible to do it at installation or boot time. The right place is in vdsm when it's trying to create the local data store. Dan, is this possible to do? Isn't /data2/images also a possible location?

[Users] Question on configuring local storage on oVirt Node
Hi folks - I hope this is the right place for this question; I have tried to Google this but in general haven't been able to find much in the way of docs outside of the main installation guide. In aforementioned guide there are instructions for configuring local-only storage on oVirt Node machines: "On a oVirt Node host, set up the path for the local storage as /data/images. This is the only path permitted for a oVirt Node. On a Red Hat Enterprise Linux host other paths are supported but the directories to support it must be manually created first." I'm probably missing something, but it's unclear to me how to create this local storage mountpoint on that host. (I don't see anything in the Node TUI.) I tried simply specifying "/data/images" in the hopes that it was automatically created, but the Admin console just spun indefinitely (eventually refreshing the page revealed that the store was note created). I'm currently rebuilding that Node as a F16+VDSM box instead -- so I can get in there and set this up manually (is there a way to get into schell on oVirt Nodes and mess with the [F16-based?] OS?) Any guidance greatly appreciated. Thanks, Hans ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [Users] Passing a hint/message to a VM when it boots
Hi, yes, using a kernel boot option would be nice, and there is an option for it in Ovirt, but I am not getting it to work. When i want to specify a boot parameter, I also have to specify a kernel path. When i specify the internal kernel, the VM fails to boot. Is this supposed to be an "external" kernel ( like paravirtualized Xen? ) On 03/16/2012 11:11 PM, Itamar Heim wrote: On 03/16/2012 03:05 PM, Kyrre Begnum wrote: 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.

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 did you try the kernel boot options?
