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

OVN and change of mgmt network
by Gianluca Cecchi 26 Jan '21

26 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

CentOS Stream support
by Michal Skrivanek 25 Jan '21

25 Jan '21

Hi all, we would like to ask about interest in community about oVirt moving to CentOS Stream. There were some requests before but it’s hard to see how many people would really like to see that. With CentOS releases lagging behind RHEL for months it’s interesting to consider moving to CentOS Stream as it is much more up to date and allows us to fix bugs faster, with less workarounds and overhead for maintaining old code. E.g. our current integration tests do not really pass on CentOS 8.1 and we can’t really do much about that other than wait for more up to date packages. It would also bring us closer to make oVirt run smoothly on RHEL as that is also much closer to Stream than it is to outdated CentOS. So..would you like us to support CentOS Stream? We don’t really have capacity to run 3 different platforms, would you still want oVirt to support CentOS Stream if it means “less support” for regular CentOS? There are some concerns about Stream being a bit less stable, do you share those concerns? Thank you for your comments, michal

encrypted GENEVE traffic
by Pavel Nakonechnyi 18 Jan '21

18 Jan '21

Dear oVirt Community, From my understanding oVirt does not support Open vSwitch IPSEC tunneling for GENEVE traffic (which is described on pages http://docs.openvswitch.org/en/latest/howto/ipsec/ and http://docs.openvswitch.org/en/latest/tutorials/ipsec/) Are there plans to introduce such support? (or explicitly not to..) Is it possible to somehow manually configure such tunneling for existing virtual networks? (even in a limited way) Alternatively, is it possible to deploy oVirt on top of the tunneled (i.e. via VXLAN, IPSec) interfaces? This will allow to encrypt all management traffic. Such requirement arises when using oVirt deployment on third-party premises with untrusted network. Thank in advance for any clarifications. :) -- WBR, Pavel +32478910884

oVirt 4.4: Self-hosted engine deployment fails with backup restore from 4.3 engine
by Oliver Leinfelder 11 Dec '20

11 Dec '20

Hi there, I'm a bit puzzled about an possible upgrade paths from a 4.3 cluster to version 4.4 in a self-hosted engine environment. My idea was: Set up a new host with a clean ovirt node 4.4 installation, then deploy the hosted engine on this with a restored backup from the production cluster and go from there. This however fails with the following error: 2020-05-27 00:17:08,886+0200 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:103 {'msg': 'non-zero return code', 'cmd': ['engine-setup', '--accept-defaults', '--config-append=/root/ovirt-engine-answers'], 'stdout': "[ INFO ] Stage: Initializing\n[ INFO ] Stage: Environment setup\n C onfiguration files: /etc/ovirt-engine-setup.conf.d/10-packaging-jboss.conf, /etc/ovirt-engine-setup.conf.d/10-packaging.conf, /etc/ovirt-engine-setup.conf.d/20-setup-ovirt-post.conf, /root/ovirt-engine-answers\n Log file: /var/log/ovirt-engine/setup/ovirt-engine-setup-20200527001657-fyeueu.log\n Version: otop i-1.9.1 (otopi-1.9.1-1.el8)\n[ INFO ] DNF Downloading 1 files, 0.00KB\n[ INFO ] DNF Downloaded CentOS-8 - AppStream\n[ INFO ] DNF Downloading 1 files, 0.00KB\n[ INFO ] DNF Downloaded CentOS-8 - Base\n[ INFO ] DNF Downloading 1 files, 0.00KB\n [...] ... anwsers from backup config follow ....

If not, what is the appropriate upgrade path? Thank you! Regards Oli

"gluster-ansible-roles is not installed on Host" error on Cockpit
by Hesham Ahmed 26 Nov '20

26 Nov '20

On a new 4.3.1 oVirt Node installation, when trying to deploy HCI (also when trying adding a new gluster volume to existing clusters) using Cockpit, an error is displayed "gluster-ansible-roles is not installed on Host. To continue deployment, please install gluster-ansible-roles on Host and try again". There is no package named gluster-ansible-roles in the repositories: [root@localhost ~]# yum install gluster-ansible-roles Loaded plugins: enabled_repos_upload, fastestmirror, imgbased-persist, package_upload, product-id, search-disabled-repos, subscription-manager, vdsmupgrade This system is not registered with an entitlement server. You can use subscription-manager to register. Loading mirror speeds from cached hostfile * ovirt-4.3-epel: mirror.horizon.vn No package gluster-ansible-roles available. Error: Nothing to do Uploading Enabled Repositories Report Cannot upload enabled repos report, is this client registered? This is due to check introduced here: https://gerrit.ovirt.org/#/c/98023/1/dashboard/src/helpers/AnsibleUtil.js Changing the line from: [ "rpm", "-qa", "gluster-ansible-roles" ], { "superuser":"require" } to [ "rpm", "-qa", "gluster-ansible" ], { "superuser":"require" } resolves the issue. The above code snippet is installed at /usr/share/cockpit/ovirt-dashboard/app.js on oVirt node and can be patched by running "sed -i 's/gluster-ansible-roles/gluster-ansible/g' /usr/share/cockpit/ovirt-dashboard/app.js && systemctl restart cockpit"
