I was using a new system with Ubuntu 20.04.
Obviously for Xen it needs a few packages installed - a bit more than in the
past even since since Xen is demoted to Universe for it's low adoption by the
community (KVM IMHO beats it in all cases).
Step #1 - prep packages:
$ sudo apt install xen-hypervisor xen-utils libvirt-daemon-driver-xen
libvirt-clients libvirt-daemon-system
Please do note that e.g. the further dependencies that you were missing
like "qemu-system-x86-xen" are pulled in via dependencies automatically.
As xen-utils-4.11 depends on it.
Step #2 - since xen needs to boot into it's special Dom0 reboot:
$ sudo reboot
After reboot check if things work so far:
$ sudo xl list
[sudo] password for ubuntu:
Name ID Mem VCPUs State Time(s)
Domain-0 0 15921 4 r----- 29.0
-- I assume you are here atm, xen working but libvirt can't connect --
# Step 3 - libvirt
Check libvirt is connected to Xen:
$ virsh --connect xen:/// list --all
Id Name State
--------------------------
0 Domain-0 running
If running in a Dom0 the xen connection is the default, but for the sake
of showing the connection URL I added it to the command.
Also capabilities probing by libvirt went well
$ virsh capabilities | grep xen
<os_type>xen</os_type>
<emulator>/usr/lib/xen-4.11/bin/qemu-system-i386</emulator>
<machine>xenpv</machine>
<domain type='xen'/>
<os_type>xen</os_type>
<emulator>/usr/lib/xen-4.11/bin/qemu-system-i386</emulator>
<machine>xenpv</machine>
<domain type='xen'/>
<emulator>/usr/lib/xen-4.11/bin/qemu-system-i386</emulator>
<loader>/usr/lib/xen-4.11/boot/hvmloader</loader>
<machine>xenfv</machine>
<domain type='xen'/>
<os_type>xenpvh</os_type>
<emulator>/usr/lib/xen-4.11/bin/qemu-system-i386</emulator>
<machine>xenpvh</machine>
<domain type='xen'/>
<emulator>/usr/lib/xen-4.11/bin/qemu-system-i386</emulator>
<loader>/usr/lib/xen-4.11/boot/hvmloader</loader>
<machine>xenfv</machine>
<domain type='xen'/>
<os_type>xenpvh</os_type>
<emulator>/usr/lib/xen-4.11/bin/qemu-system-i386</emulator>
<machine>xenpvh</machine>
<domain type='xen'/>
Step #4 - virt-manager
So libvirt is able to talk&work with Xen it seems, your error report was from
virt-manager.
Therefore let me install that.
$ sudo apt install virt-manager
$ virt-manager
This gets me into virt-manager also auto-connecting with Xen.
(screenshot attached)
Step #5 - install something from virt-manager
$ wget https://releases.ubuntu.com/20.04/ubuntu-20.04-live-server-amd64.iso
$ sudo mv ubuntu-20.04-live-server-amd64.iso /var/lib/libvirt/images/
Then in virt-manager
- New
- From local ISO
- select ISO
- forward
- forward(keep defaults)
- forward (get me storage)
- Finish will get you into trouble because the defaults are bad, but not into
the connection issues you had.
The error is more like "/usr/lib/xen-4.11/bin/qemu-system-i386 not found"
>From here either modify the wrong defaults in the guest config for the
>Emulator from /usr/lib/xen-4.11/bin/qemu-system-i386 to the correct
>/usr/bin/qemu-system-i386 or symlink the former to the latter.
$ sudo ln -s /usr/bin/qemu-system-i386 /usr/lib/xen-4.11/bin/qemu-
system-i386
- press Finish and install will begin
You see it works fine (ignoring the small hickup on the binary path) and
I can't recreate your issue. It would be great if you could consider
trying the very same steps on a clean system to check when/where your
troubles begin.
