Hugepages and running out of memory
by klaasdemter＠gmail.com 22 Feb '20

22 Feb '20

Hi, this e-mail is meant to caution people using hugepages and mixing those VMs with non-hugepages VMs on the same hypervisors. I ran into major trouble, the hypervisors ran out of memory because the VM scheduling disregards the hugepages in it's calculations. So if you have hugepages and non-hugepages VMs better check the memory commited on a hypervisor manually :) https://bugzilla.redhat.com/show_bug.cgi?id=1804037 https://bugzilla.redhat.com/show_bug.cgi?id=1804046 As for workarounds: so far it seems the only viable solution is splitting hugepages/nonhugepages VMs with affinity groups but at least for me that means wasting a lot of resources. Greetings Klaas

main channel: failed to connect HTTP proxy connection not allowed

Hi, Having a spice console issue on our new 4.3.8 cluster. The console stays blank and with the cli and debug on, I get the following error "main channel: failed to connect HTTP proxy connection not allowed" We have a userportal through haproxy so this is configured in ovirt engine engine-config -g SpiceProxyDefault SpiceProxyDefault: http://userportal.*.*:****/ version: general But the same setting works fine on our 4.2 cluster. I can telnet to the ports on the 4.3.8 hosts without issue. Non working console on newer cluster: remote-viewer -v --debug console.vv (remote-viewer:29267): virt-viewer-DEBUG: 16:24:24.697: Opening display to console.vv (remote-viewer:29267): virt-viewer-DEBUG: 16:24:24.700: Guest (null) has a spice display Guest (null) has a spice display (remote-viewer:29267): virt-viewer-DEBUG: 16:24:24.789: Spice foreign menu updated (remote-viewer:29267): virt-viewer-DEBUG: 16:24:24.790: After open connection callback fd=-1 (remote-viewer:29267): virt-viewer-DEBUG: 16:24:24.790: Opening connection to display at console.vv Opening connection to display at console.vv (remote-viewer:29267): virt-viewer-DEBUG: 16:24:24.791: fullscreen display 0: 0 (remote-viewer:29267): virt-viewer-DEBUG: 16:24:24.791: app is not in full screen (remote-viewer:29267): virt-viewer-DEBUG: 16:24:24.792: New spice channel 0x55704bf70d40 SpiceMainChannel 0 (remote-viewer:29267): virt-viewer-DEBUG: 16:24:24.793: notebook show status 0x55704b820280 (remote-viewer:29267): virt-viewer-DEBUG: 16:24:24.969: main channel: failed to connect HTTP proxy connection not allowed (remote-viewer:29267): virt-viewer-DEBUG: 16:24:24.969: Destroy SPICE channel SpiceMainChannel 0 (remote-viewer:29267): virt-viewer-DEBUG: 16:24:24.969: zap main channel (remote-viewer:29267): virt-viewer-WARNING **: 16:24:24.969: Channel error: HTTP proxy connection not allowed Working console on older cluster: remote-viewer -v --debug console.vv (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.111: Opening display to console.vv (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.111: Guest (null) has a spice display Guest (null) has a spice display (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.209: Spice foreign menu updated (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.209: After open connection callback fd=-1 (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.209: Opening connection to display at console.vv Opening connection to display at console.vv (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.211: fullscreen display 0: 0 (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.211: app is not in full screen (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.212: New spice channel 0x556a03f7e820 SpiceMainChannel 0 (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.212: notebook show status 0x556a03c7a280 (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.397: main channel: opened (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.397: notebook show status 0x556a03c7a280 (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.404: virt_viewer_app_set_uuid_string: UUID changed to a2d64ffe-7583-45b6-92f3-87661039388c (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.404: app is not in full screen (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.502: app is not in full screen (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.514: New spice channel 0x556a043bb660 SpiceDisplayChannel 0 (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.514: New spice channel 0x556a0422b570 SpiceCursorChannel 0 (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.515: New spice channel 0x556a0422c000 SpiceInputsChannel 0 (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.515: new inputs channel (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.661: creating spice display (#:0) (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.661: Insert display 0 0x556a03ca29e0 (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.699: creating spice display (#:1) (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.699: Insert display 1 0x556a03ca2830 (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.699: creating spice display (#:2) (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.700: Insert display 2 0x556a03ca2680 (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.700: creating spice display (#:3) (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.700: Insert display 3 0x556a03ca24d0 (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.701: Found a window without a display, reusing for display #0 (remote-viewer:29334): virt-viewer-DEBUG: 16:25:59.701: notebook show display 0x556a03c7a280 (remote-viewer:29334): virt-viewer-DEBUG: 16:26:00.074: Allocated 1024x768 (remote-viewer:29334): virt-viewer-DEBUG: 16:26:00.074: Child allocate 1024x768 (remote-viewer:29334): virt-viewer-DEBUG: 16:26:04.846: Allocated 1024x768 (remote-viewer:29334): virt-viewer-DEBUG: 16:26:04.846: Child allocate 1024x768 Met vriendelijke groet, With kind regards, Jorick Astrego Netbulae Virtualization Experts ---------------- Tel: 053 20 30 270 info(a)netbulae.eu Staalsteden 4-3A KvK 08198180 Fax: 053 20 30 271 www.netbulae.eu 7547 TA Enschede BTW NL821234584B01 ----------------

Understanding dashboard memory data
by nux＠li.nux.ro 21 Feb '20

21 Feb '20

Hello, I'm having to deal with an oVirt installation, once I log in the dashboard says: Memory: "1.2 Available of 4.5 TiB" and "Virtual resources - Committed: 113%, Allocated: 114%". So, clearly there is RAM available, but what's with the committed and allocated numbers? Regards

Ovirt storage domain ovirt-image-repository is unattached and can't use change CD to install windows on VM
by Heinrich Momberg 20 Feb '20

20 Feb '20

Good day, Whenever i am trying to use the change CD to mount the ovirt tools iso so i can install windows server or any windows it says "could not find ISO file collection".It doesn't pick up the hdd that i have created in the windwos setup so i have to do the whole ovirt tools mount and select the windows i want to insteall etc. It has been working fine until a couple of days ago when we had power outages. I also noticed that the storage domain,ovirt-image-repository is unattached... How do i go about fixing this problem or where can i check logs. I have checked the permissions where the ISO's or images are stored.

Spacewalk Integration
by eevans＠digitaldatatechs.com 20 Feb '20

20 Feb '20

I finally figured out how to use Spacewalk as an external provider in Ovirt. For the URL I used http://sat.digitaldatatechs.com/XMLRPC and used the admin login credentials. It registered and Spacewalk has the capability of provisioning a bare bones machine. I have not tested provisioning but I will comment once I do.

20 Feb '20

Hello guys, how can I get the correct CPU Family in a ovirt host? When I execute virsh -r capabilities I get only "Broadwell-noTSX-IBRS" and not the full "Broadwell-noTSX IBRS SSBD MDS" Regards, Luca

Unsynced entries do not self-heal during upgrade from oVirt 4.2 -> 4.3
by Goorkate, B.J. 20 Feb '20

20 Feb '20

Hi all, I'm in the process of upgrading oVirt-nodes from 4.2 to 4.3. After upgrading the first of 3 oVirt/gluster nodes, there are between 600-1200 unsynced entries for a week now on 1 upgraded node and one not-yet-upgraded node. The third node (also not-yet-upgraded) says it's OK (no unsynced entries). The cluster doesn't seem to be very busy, but somehow self-heal doesn't complete. Is this because of different gluster versions across the nodes and will it resolve as soon as I upgraded all nodes? Since it's our production cluster, I don't want to take any risk... Does anybody recognise this problem? Of course I can provide more information if necessary. Any hints on troubleshooting the unsynced entries are more than welcome! Thanks in advance!
