Comment 19 for bug 1982896

I followed the steps to enable installation of "proposed" packages:
https://wiki.ubuntu.com/Testing/EnableProposed

But I had problems with "$ sudo apt-get upgrade -s": no libvirt packages were listed.
(Running "sudo aptitude -t jammy-proposed" revealed various dependencies issues holding back libvirt packages.)

I ended up installing the libvirt packages manually:

...
$ sudo apt-get install libvirt-clients/jammy-proposed
$ sudo apt-get install libvirt-daemon-system/jammy-proposed
$ sudo apt-get install libvirt-daemon-config-network/jammy-proposed
...

This allowed me to install 8.0.0-1ubuntu7.7 versions of libvirt packages from "jammy-proposed":

$ sudo apt list --installed | grep libvirt

gir1.2-libvirt-glib-1.0/jammy,now 4.0.0-2 amd64 [installed,automatic]
libvirt-clients/jammy-proposed,now 8.0.0-1ubuntu7.7 amd64 [installed]

libvirt0/jammy-proposed,now 8.0.0-1ubuntu7.7 amd64 [installed,automatic]
python3-libvirt/jammy,now 8.0.0-1build1 amd64 [installed,automatic]

After that I restarted and verified libvirtd:

$ sudo systemctl restart libvirtd
$ sudo systemctl status libvirtd

After that I was able to launch a VM with SGX enabled as described in comment #11 above.

The conclusion: once the libvirt packages are installed, they work as expected.
