Snapshot and disk size allocation
by jorgevisentini＠gmail.com 29 Oct '21

29 Oct '21

Hello everyone. I would like to know how disk size and snapshot allocation works, because every time I create a new snapshot, it increases 1 GB in the VM's disk size, and when I remove the snap, that space is not returned to Domain Storage. I'm using the oVirt 4.3.10 How do I reprovision the VM disk? Thank you all.

oVirt 4.3 DWH with Grafana
by Vrgotic, Marko 15 Sep '21

15 Sep '21

Dear oVirt, We are currently running oVirt 4.3 and upgrade/migration to 4.4 won’t be possible for few more months. I am looking into guidelines, how to, for setting up Grafana using DataWarehouse as data source. Did anyone already did this, and would be willing to share the steps? Kindly awaiting your reply. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

Template for Ubuntu 18.04 Server Issues
by jeremy_tourville＠hotmail.com 03 Sep '21

03 Sep '21

I have built a system as a template on oVirt. Specifically, Ubuntu 18.04 server. I am noticing an issue when creating new vms from that template. I used the check box for "seal template" when creating the template. When I create a new Ubuntu VM I am getting duplicate IP addresses for all the machines created from the template. It seems like the checkbox doesn't fully function as intended. I would need to do further manual steps to clear up this issue. Has anyone else noticed this behavior? Is this expected or have I missed something? Thanks for your input!

Libgfapi considerations
by Jayme 01 Jul '21

01 Jul '21

Are there currently any known issues with using libgfapi in the latest stable version of ovirt in hci deployments? I have recently enabled it and have noticed a significant (over 4x) increase in io performance on my vms. I’m concerned however since it does not seem to be an ovirt default setting. Is libgfapi considered safe and stable to use in ovirt 4.3 hci?

supervdsm failing during network_caps
by Alan G 24 Mar '21

24 Mar '21

Hi, I have issues with one host where supervdsm is failing in network_caps. I see the following trace in the log. MainProcess|jsonrpc/1::ERROR::2020-01-06 03:01:05,558::supervdsm_server::100::SuperVdsm.ServerCallback::(wrapper) Error in network_caps Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/supervdsm_server.py", line 98, in wrapper res = func(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/network/api.py", line 56, in network_caps return netswitch.configurator.netcaps(compatibility=30600) File "/usr/lib/python2.7/site-packages/vdsm/network/netswitch/configurator.py", line 317, in netcaps net_caps = netinfo(compatibility=compatibility) File "/usr/lib/python2.7/site-packages/vdsm/network/netswitch/configurator.py", line 325, in netinfo _netinfo = netinfo_get(vdsmnets, compatibility) File "/usr/lib/python2.7/site-packages/vdsm/network/netinfo/cache.py", line 150, in get return _stringify_mtus(_get(vdsmnets)) File "/usr/lib/python2.7/site-packages/vdsm/network/netinfo/cache.py", line 59, in _get ipaddrs = getIpAddrs() File "/usr/lib/python2.7/site-packages/vdsm/network/netinfo/addresses.py", line 72, in getIpAddrs for addr in nl_addr.iter_addrs(): File "/usr/lib/python2.7/site-packages/vdsm/network/netlink/addr.py", line 33, in iter_addrs with _nl_addr_cache(sock) as addr_cache: File "/usr/lib64/python2.7/contextlib.py", line 17, in __enter__ return self.gen.next() File "/usr/lib/python2.7/site-packages/vdsm/network/netlink/__init__.py", line 92, in _cache_manager cache = cache_allocator(sock) File "/usr/lib/python2.7/site-packages/vdsm/network/netlink/libnl.py", line 469, in rtnl_addr_alloc_cache raise IOError(-err, nl_geterror(err)) IOError: [Errno 16] Message sequence number mismatch A restart of supervdsm will resolve the issue for a period, maybe 24 hours, then it will occur again. So I'm thinking it's resource exhaustion or a leak of some kind? Running 4.2.8.2 with VDSM at 4.20.46. I've had a look through the bugzilla and can't find an exact match, closest was this one https://bugzilla.redhat.com/show_bug.cgi?id=1666123 which seems to be a RHV only fix. Thanks, Alan

Gluster volume slower then raid1 zpool speed
by Harry O 29 Jan '21

29 Jan '21

Hi, Can anyone help me with the performance on my 3 node gluster on zfs (it is setup with one arbiter) The performance on the single vm I have on it (with engine) is 50% worse then a single bare metal disk, on the writes. I have enabled "Optimize for virt store" I run 1Gbps 1500MTU network, could this be the write performance killer? Is this to be expected from a 2xHDD zfs raid one on each node, with 3xNode arbiter setup? Maybe I should move to raid 5 or 6? Maybe I should add SSD cache to raid1 zfs zpools? What are your thoughts? What to do for optimize this setup? I would like to run zfs with gluster and I can deal with a little performance loss, but not that much.

OVN and change of mgmt network
by Gianluca Cecchi 27 Jan '21

27 Jan '21

Hello, I previously had OVN running on engine (as OVN provider with northd and northbound and southbound DBs) and hosts (with OVN controller). After changing mgmt ip of hosts (engine has retained instead the same ip), I executed again on them the command: vdsm-tool ovn-config <ip_of_engine> <nel_local_ip_of_host> Now I think I have to clean up some things, eg: 1) On engine where I get these lines below systemctl status ovn-northd.service -l . . . Sep 29 14:41:42 ovmgr1 ovsdb-server[940]: ovs|00005|reconnect|ERR|tcp: 10.4.167.40:37272: no response to inactivity probe after 5 seconds, disconnecting Oct 03 11:52:00 ovmgr1 ovsdb-server[940]: ovs|00006|reconnect|ERR|tcp: 10.4.167.41:52078: no response to inactivity probe after 5 seconds, disconnecting The two IPs are the old ones of two hosts It seems that a restart of the services has fixed... Can anyone confirm if I have to do anything else? 2) On hosts (there are 3 hosts with OVN on ip 10.4.192.32/33/34) where I currently have this output [root@ov301 ~]# ovs-vsctl show 3a38c5bb-0abf-493d-a2e6-345af8aedfe3 Bridge br-int fail_mode: secure Port "ovn-1dce5b-0" Interface "ovn-1dce5b-0" type: geneve options: {csum="true", key=flow, remote_ip="10.4.192.32"} Port "ovn-ddecf0-0" Interface "ovn-ddecf0-0" type: geneve options: {csum="true", key=flow, remote_ip="10.4.192.33"} Port "ovn-fd413b-0" Interface "ovn-fd413b-0" type: geneve options: {csum="true", key=flow, remote_ip="10.4.168.74"} Port br-int Interface br-int type: internal ovs_version: "2.7.2" [root@ov301 ~]# The IPs of kind 10.4.192.x are ok. But there is a left-over of an old host I initially used for tests, corresponding to 10.4.168.74, that now doesn't exist anymore How can I clean records for 1) and 2)? Thanks, Gianluca
