getting 404 after fresh install of oVirt 3.4 on CentOS 6.5 (+ solution)
by Steven Van Acker 13 May '14

13 May '14

Hello all, I was asked to post the following problem on this mailinglist. After installing a clean CentOS 6.5 with a clean oVirt 3.4, following the instructions from http://www.ovirt.org/Download#Red_Hat_Enterprise_Linux_6.2FCentOS_Installat… I went to http://localhost.localdomain:80/ovirt-engine as indicated and was redirected to a 404 page. The same happened when using https. During the installation, engine-setup will print out the following on my VM with 512MB RAM: [WARNING] Warning: Not enough memory is available on the host. Minimum requirement is 4096MB, and 16384MB is recommended. SSH fingerprint: 4B:DE:48:26:99:AA:C0:72:E3:C8:B5:64:5F:6E:6D:00 Internal CA FB:82:FE:14:35:3A:BE:1A:B1:E6:99:C2:DC:CD:6D:E0:44:64:0F:47 Web access is enabled at: http://localhost.localdomain:80/ovirt-engine https://localhost.localdomain:443/ovirt-engine Please use the user "admin" and password specified in order to login into oVirt Engine The consequence of not having enough RAM for oVirt is that it will silently fail to start up, without apparent errors or warnings. In my view, the warning above should be rephrased as "Not enough memory is available on the host, oVirt will refuse to start" and colored red. The solution to this problem is to have at least 4GB of RAM, after which oVirt seems to start up fine (with only 1.2GB of RAM in use). kr, -- Steven

Underlying FS is XFS GlusterFS - glusterfs-3.5.0-2.el6 I'm using CentOS, if this is problem could RHEL packages be used? why CentOS packages are compiled without native glusterfs support?

help with sriov vdsm hook?
by Darrell Budic 12 May '14

12 May '14

Anyone gotten the SRIOV hook to work with Solar Flare 10g cards? Any advice? I've gotten the hooks installed on my host nodes, and added a string to my engine. The card is up in SRIOV "mode" on the host and virtual instances are available. I can see the hooks running in the vdsm logs, but can't tell what they are doing from there. They are not attaching the sriov card instance to my VM though, so I'm at a loss. As an aside, it'd be really nice to have hooks register with the engine and add proper custom strings to the setup. Failing that, some explicit documentation on EXACTLY what string should be used for the hook would be nice. My first pass at it resulted in an improper string that caused my host to crash/hang and reboot when I attempted to start a VM with it the first time. Speaking of which, I added my custom string to UserDefinedVMProperties, not CustomDeviceProperties. Was that correct? Thanks, -Darrell

storage randomly going non responsive for long times and then coming back just on this machine. the storage nfs server replies to pings so it's not the connection.
