Upgrade 4.1 to 4.2 lsot gfapi Disk Access for VM's

by Ralf Schenk

Hello, after upgradeing my whole cluster of 8 Hosts to ovirt 4.2.5 and setting compability of cluster and datacenter to 4.2 my existing virtual machines start using FUSE mounted disk-images on my gluster volumes. One bad and slow thing I thought that I got rid of starting with 4.1.x finally ! Disk definition from virsh -r dumpxml VM of old running vm (not restarted yet !): <disk type='network' device='disk' snapshot='no'> <driver … [View More]

info about changing engine ip mode from dhcp to static

by Gianluca Cecchi

Hello, a colleague of mine installed oVirt engine 4.2.5 on a test CentOS 7.5 system and in its initial configuration he configured its ip via dhcp (using static ip assignment configured at dhcp server side). Now he would like to maintain the same ip/hostname for the engine but with a static configuration on the server. Any hint about how to achieve this? Thanks in advance, Gianluca

Poor performance of oVirt Export Domain

Hello I deployed a dedicated server (fs05.holding.com) on CentOS 7.5 and created a VDO volume on it.

oVirt 4.2.5 : VM snapshot creation does not work : command HSMGetAllTasksStatusesVDS failed: Could not acquire resource

by Aleksey Maksimov

Hello We use oVirt 4.2.5.2-1.el7 (Hosted engine / 4 hosts in cluster / about twenty virtual machines) Virtual machine disks are located on the Data Domain from FC SAN.

Clarifications regarding ovirt-provider-ovn network

by Anurag Porripireddi

Hi, I had some questions a overt-provider-ovn based external network which is built on top of an physical network. I notice that VLAN tagging gets greyed out when I try to create an external provider network. Is it not supported by overt right now?I am on version 4.2.5.3. Also, if I create NICs with the external provider network built atop a physical network on VMs that are on different hosts, but the same cluster, I see they are unable to ping each other, though it seems to work fine if they … [View More]
