by Lev Veyde 25 Mar '21

25 Mar '21

oVirt 4.4.6 First Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.6 First Release Candidate for testing, as of March 25th, 2021. This update is the sixth in a series of stabilization updates to the 4.4 series. How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Note: Upgrading from 4.4.2 GA or later should not require re-doing these steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only required to be done once. Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> - Host enter emergency mode after upgrading to latest build If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.6 you may get your host entering emergency mode. In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts: 1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted). 2. Reboot. 3. Upgrade to 4.4.6 (redeploy in case of already being on 4.4.6). 4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place. 5. Only if not using oVirt Node: - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration 6. Reboot. Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>. Important notes before you try it Please note this is a pre-release build. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not be used in production. Installation instructions For installation instructions and additional information please refer to: https://ovirt.org/documentation/ This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.3 or newer * CentOS Linux (or similar) 8.3 or newer This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.3 or newer * CentOS Linux (or similar) 8.3 or newer * oVirt Node 4.4 based on CentOS Linux 8.3 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed.

Ovirt Node (iso) - OK to enable Centos-BaseOS/Centos-Appstream repos ?
by morgan cox 25 Mar '21

25 Mar '21

Hi. I have installed Ovirt nodes via the ovirt-node iso (centos8 based) - on a fresh install the standard CentOS repos are disabled (the ovirt 4-4 repo is enabled) As part of our company hardening we need to install a few packages from the Centos repos. Can I enable the CentOS-Linux-AppStream.repo + CentOS-Linux-BaseOS.repo repos or will this cause issues when we update the node ? Thanks

Problem to create provider
by miguel.garcia＠toshibagcs.com 25 Mar '21

25 Mar '21

We have a problem to create the first provider in the ovirt cluster by following next steps: Go to Administration - Provider - click Add Filled up fields for new provider with next information: Name: ovirt-provider-ovn Type: External Network Provider Network Plugin: oVirt Network Provider for OVN Provider URL: https://ovirthostname:9696 Uncheck Read-only Check Request authentication username : admin@internal Protocol HTTPS Hostname ovirthostname API port: 35357 Click Test Result: Test Failed (unknow error) Log file: 2021-03-23 15:23:50,986-04 ERROR [org.ovirt.engine.core.bll.provider.network.openstack.ExternalNetworkProviderProxy] (default task-118) [501852ef-cd76-40d0-8ef3-6b0826b3c0dd] Failed to communicate with external provider 'ovirt-provider-ovn' due to error 'ConnectException: Connection refused (Connection refused)' [org.ovirt.engine.core.utils.servlet.ServletUtils] (default t2021-03-23 15:23:50,986-04 ERROR [org.ovirt.engine.core.bll.GetProviderCertificateChainQuery] (default task-118) [501852ef-cd76-40d0-8ef3-6b0826b3c0dd] Error in encoding certificate: EngineException: Connection refused (Connection refused) (Failed with error PROVIDER_FAILURE and code 5050) I think I would expect to ask the certificate to complete connection but does not ask for certificate at all. Any idea how to solve this?

VDSM command failed:Received fatal alert certificate_expire
by fmendoza＠red.com.sv 24 Mar '21

24 Mar '21

Recently Ovirt sent certificate expiration messages. And it does not let me manage the server VMs, I have looked for information about this and I can not find something that is clear. The version of Ovirt that I own is 3.6.3.4-1.el7.cents. I have at least 4 operational VMs of vital importance. Thanks for the support

websockify + ovirt

Hi, I am trying to get the spice-web-client working with ovirt. One area where I am having difficulties is authentication.Looking at remote-viewer on linux I am able to see that the minimum fields to have a successful spice connection are the following: [virt-viewer] type=spice host=70.xxx.176.xxx port=5914 password=WQJQWCo+s8tK tls-port=5915 tls-ciphers=DEFAULT host-subject=O=xxxx.com,CN=d1c1v5.xxx.net ca=-----BEGIN CERTIFICATE-----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\nMA4GA1UdDwEB/wQEAwIBBjANBgkqhkiG9w0BAQsFAAOCA QEAoC8Nx/s4Uafgc3iyzxbLPb/chQ8U\n7+lULXTq+ZLOuMDdu6UKt7qKZpJZK8ZhjFh/1yVOnpzm7Np+oP7TQlOUkup8X4HsfAwrCgNK1IT1\nETdbdMYD8HYFjxz/0xbnMkJAHfPEh1vtqplw3YhVgiAZfZfT8HzVY/xGkjurvxSyVjBSbn+4uao1\n6W9URt2rWTHn+XxoT+j+cx8vv1WKsynlMBtUjCFy8eR7ZDngRcM/9iRkRCGHJvWJmi1CRrQeE5RZ\nvBH0zE64J3cOJj4BSlN3wOYWiRq28XLB9epDDyZaRpnsqLCOq/+/LscM7iPW1acdCoCu68nJUwTQ\nh1Jh7vQjCQ==\n-----END CERTIFICATE-----\n with this I can successfully connect to a vm. Now I would like to do the same from spice-web-client but websockify doesn't give me a tls-port. How to could I implement this? Is there a wrapper that exists that I can pass to websockify to do the authentication on the port + 1 (it seems it is always the next port) Thanks in advance for your help

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

The best HCI config with 8Nodes and 2 sites?
by Arman Khalatyan 23 Mar '21

23 Mar '21

Hello everybody, I would like to deploy HCI with our 2 buildings each with 8 compute nodes. Each host has a mirrored OS disks and 1 slot for the SSD. So I will use SSD for the glusterfs. my question is what is the best type of the glusterfs volume? I can leave with 8way mirror but what happened if the connection between buildings will go down? where will my ovirt-engine start?
