Why so long to add virtual HDD?
by Alan Murrell 18 May '15

18 May '15

Hello, I am wondering why it takes so long to provision a HDD for a VM? I typically do full provision (as opposed to "thin" provision) and while I have never sat there and timed it, it takes at least ten minutes to provision a 32GB HDD. I provisioned a 100GB HDD earlier today and even after 45 minutes it was not complete. I am from the VMware world where it takes less than a minute (usually more like 30 seconds or so) to provision a VM, regardless of HDD assigned. My host's physical HDD's are 2x2TB SATA drives in a hardware RAID1. oVirt storage is an NFS pool connecting to my host machine (for all intents and purposes, local storage) I wonder if I have things mis-configured? Is it normal for provisioning to take that long? Thanks! :-) -Alan

missing disk after storage domain expansion
by Andrea Ghelardi 18 May '15

18 May '15

Hi gentlemen, I recently found an error on 1 of my storages: it was complaining about no free space but the VM was running and disk operational. Since I needed to perform some maintenance on the VM, I shut it down and at restart VM couldn’t boot up properly. Checked VM via console and a disk was missing. Edited fstab (luckily this disk was not root but heck! It had a Sybase DB on it!) and restarted VM this time ok. Since the disk resides on the dstore with no space, I expanded the iSCSI LUN, then refreshed multipath on hosts, then resized PVs and now ovirt is showing the correct size (logs do not complain anymore on no free space). BUUUT Now disk is missing. It is not shown anymore on Disks tab nor anywhere else. Problem is that storage shows 214GB occupancy (size of the missing disk) so data is there but cannot find it anymore. Logs show original disk creation, errors from the lack of space, refresh of the storage size and then.... no more references on the disk. What can I do to find those missing ~210GBs? Cheers Andrea Ghelardi

Possible SELinux problems with ovirt syncronizing networks
by Jeremy Utley 18 May '15

18 May '15

Hello all! Running ovirt 3.5 on CentOS 7 currently, and running into a little problem. All my nodes are currently showing the ovirtmgmt network as unsyncronized. When I try to force them to sync, it fails. Looking at the /var/log/vdsm/supervdsm.log file on one of the nodes, it looks like it has to do with SELinux. See: http://pastebin.com/NX7yetVW Which contains a dump of the supervdsm.log file when I tried to force syncronization. Judging from what I'm seeing, after VDSM writes the new network configuration files to /etc/sysconfig/network-scripts/ifcfg-*, it attempts to run a selinux.restorecon function against those files. Since we disable SELinux by default on all our servers, this action is failing with Errno 61 (see lines 66-71 and 86-91 in the above-mentioned pastebin). Is this normal? Is ovirt expecting to run with SELinux enabled? Or am I mis-interpreting this log output? Thanks for any help or advice you can give me! Jeremy

My feedback on network setting after installing OVirt
by John Joseph 18 May '15

18 May '15

Hi All, Like to give my feedback about how the network interface behaved after OVirt I have used CentOS 6.6 64 bit, updated Ovirt stable from the repo Now after the installation, and configuration you get "ovirtmgmt" interface and "ovirtmgmt" interface gets the IP address and everything is fine . Now reboot it result is that when you give ifconfig , eth0 is not displayed and "ovirtmgmt" do not have IP address This stage solved by giving ifconfig eth0 up and restarting the network, it will give "ovirtmgmt" an IP now I tested it using different installation, with DHCP or manual configuration for eth0 , in both the case the same experience Giving my feedback, thanks

ovirt-agent: is it possible to run specific actions when taking snapshots?
