Re: libvirtd: failed to connect to socket after installation

Hello, made some progress and I think I see what the issue may be now... and it looks like virt-install's fault. https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Flibvirt... and ensure you're So, I started again from scratch. Deleted absolutely everything that had to do with libvirt. I also had to unmask a bunch of service-related stuff that were on masked state: for ANNOYING_SERVICE in libvirtd virtlogd.socket virtlogd.service \         virtlockd.socket virtlockd.service virtlogd-admin.socket virtlockd-admin.socket do         systemctl unmask $ANNOYING_SERVICE done So, after doing this, building and installing the tree, reloading the daemon, and starting all services and sockets again, I finally get an active libvirtd daemon: # systemctl status libvirtd ● libvirtd.service - Virtualization daemon      Loaded: loaded (/usr/local/lib/systemd/system/libvirtd.service; enabled; vendor preset: enabled)      Active: active (running) since Thu 2022-09-08 15:51:39 UTC; 1min 30s ago        Docs: man:libvirtd(8)              https://libvirt.org    Main PID: 2429457 (libvirtd)       Tasks: 20 (limit: 32768)      Memory: 55.6M         CPU: 28ms      CGroup: /system.slice/libvirtd.service              ├─   2760 /usr/sbin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/default.conf --leasefile-ro --dhcp-script=/usr/lib/libvirt/libvirt_leaseshelper              ├─   2761 /usr/sbin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/default.conf --leasefile-ro --dhcp-script=/usr/lib/libvirt/libvirt_leaseshelper              └─2429457 /usr/local/sbin/libvirtd --timeout 120 Sep 08 15:51:39 host systemd[1]: Starting Virtualization daemon... Sep 08 15:51:39 host systemd[1]: Started Virtualization daemon. # Now, this is when things get interesting... The next step is testing virt-install. Since I removed it, I proceed to install again: # sudo apt install -y virtinst (...) Unpacking virtinst (1:4.0.0-1) ... Setting up libvirt-glib-1.0-data (4.0.0-2) ...

As you can see, virtinst also installs the libvirt daemon. I didn't think this would be an issue because the libvirtd daemon running is still my version. However, when I try to do virt-install I get: # virt-install --connect qemu:///system --name ubuntu-sev \ --boot loader=/usr/share/OVMF/OVMF_CODE.fd,loader.readonly=yes,loader.type=pflash,nvram.template=/usr/share/OVMF/OVMF_VARS.fd,loader_secure=no \ --vcpus 8 --memory 4096 --memtune hard_limit=16777216 \ --disk pool=default,device=disk,size=32,format=raw \ --controller type=scsi,model=virtio-scsi  --network bridge=virbr0,model=virtio \ --controller type=virtio-serial --machine q35 --cpu host-passthrough \ --cdrom /var/lib/libvirt/images/ubuntu.iso --osinfo detect=on,require=on \ --launchSecurity sev,policy=0x00 --graphics none --tpm none ERROR    Failed to connect socket to '/var/run/libvirt/virtqemud-sock': No such file or directory # So, back to square one. However, notice that virtqemud is one of the modular daemons. So, I believe that what happens is that virt-install assumes libvirt is using the new daemon mode. Is this something that can be configured? I don't see that option in the man pages of virt-install. repo in Thanks, Carlos
