oVirt monitoring
by Ryan Nix 19 Oct '14

19 Oct '14

Hello, I was looking for something to monitor the resources managed by oVirt and not necessarily oVirt itself. It looks like there is a page on Nagios integration, however, I'm getting a 503 when trying to access the site. http://www.ovirt.org/Features/Nagios_Integration Does anyone have any recommendations on monitoring resources managed by oVirt? Thanks, Ryn

iSCSI - recommended LUN size?
by Anthony Alba 18 Oct '14

18 Oct '14

Some noob questions on iSCSI as I am doing an evaluation on NFS vs iSCSI. 1. Is there a best practices guide to LUN sizing for oVirt? E.g. N x 200G, N x 500G, N x 1 TB. http://www.ovirt.org/Quick_Start_Guide#Create_an_iSCSI_Data_Domain "oVirt platform supports iSCSI storage domains spanning multiple pre-defined Logical Unit Numbers (LUNs)." 2. Since we can extend the storage domain, I was thinking of multiples of 200G. Any reason not to do it this way? >From the mailing list: https://www.mail-archive.com/users@ovirt.org/msg13638.html "please note: - you can extend a *storage domain* by adding an extra LUN to it from ovirt-engine." 3. Any production experience with LIO target/targetcli as backend? Thanks! - Anthony

How to fix wrong speed of the Infiniband Interfaces?
by Arman Khalatyan 18 Oct '14

18 Oct '14

Hi, I am using ovirt 3.4.4-1. On the hosts I have 1Gbit(eth),10Gbit(eth) and 40Gbit(QDRInfiniband) interfaces. ib interface is used for the VM migration and iscsi disks. If I go to the network interfaces I can see right speed for eth cards. Unfortunately the IB interface speed is detected as 0b/s. This causes very hi load information on vm migrate face. Which is not true. IB can up to 2GB/s but already on 200MB/s load the hosts interfaces are overloaded. Where can I put the correct speed of IB interface? Thanks, Arman.
