| Fixed In Version: | vdsm-4.40.13 | Doc Type: | Removed functionality |
| Doc Text: |
The current version of RHV removes libvirt packages that provided non-socket activation. Now it contains only libvirt versions that provide socket activation. Socket activation provides better resource handling: There is no dedicated active daemon; libvirt is activated for certain tasks and then exits.

libvirtd is not configured in RHVH, it will be configured when adding it as a host. If you want to do it manually, you can run vdsm-tool configure --force. I don't think it's a bug (In reply to Yuval Turgeman from comment #1) > libvirtd is not configured in RHVH, it will be configured when adding it as > a host. If you want to do it manually, you can run vdsm-tool configure > --force. I don't think it's a bug Installing the hosted engine with cockpit require libvirtd to be running (or at least able to start). When libvirtd cant start we get this: https://bugzilla.redhat.com/show_bug.cgi?id=1817352 (In reply to Gal Zaidman from comment #0) > looking into libvirt config at: /etc/sysconfig/libvirtd we can see the --listen arg is added by VDSM then the auto detection code must have failed. Marcin, can't we drop it altogether? We don't need to support any older libvirt anyway, so why not just drop the whole section? Yes, it failed, Marcin and I discussed this, and you're probably right we should drop it, but there's another issue - the post install scripts run inside a chroot, so vdsm-tool which calls `systemctl show` will not work as well, unless we set the hidden environment variable SYSTEMD_IGNORE_CHROOT, which is probably bad. If we could replace the calls from show to "is-active/is-enabled" in vdsm-tool it should work *** Bug 1817352 has been marked as a duplicate of this bug. *** (In reply to Michal Skrivanek from comment #3) > (In reply to Gal Zaidman from comment #0) > > looking into libvirt config at: /etc/sysconfig/libvirtd we can see the --listen arg is added by VDSM > > then the auto detection code must have failed. > > Marcin, can't we drop it altogether? We don't need to support any older > libvirt anyway, so why not just drop the whole section? Yes, the patches I posted completely drop support for libvirt that doesn't have socket activation. Test version:
redhat-virtualization-host-4.4.0-20200408.1.el8_2
vdsm-4.40.13-1.el8ev.x86_64
Test steps:
1. Install RHVH-4.4-20200408.0-RHVH-x86_64-dvd1.iso via anaconda GUI.
2. run systemctl start libcvirtd
3. Register to engine(4.4.0-0.26.master.el8ev).
Test result:
1. Libvirt service can start succeed.
2. Register to engine can succeed.
