Overall, what is the compatibility with .vbox files? Can KVM or gnome-boxes read them, or is there a significant conversion process required?
The
qemu-img command should be able to convert disk images between various formats:

Yes that is correct.
""usermod -aG libvirt $USER"
This I think allows the non root user to use Virtual Manager from the desktop icon and connect to libvirt.
BUT you can also run it from a terminal like this
"sudo virt-manager"
In KVM you do NOT need to explicitly add any packages on the guests.It works out of the box.
I am unaware if this is the case also in gnome-boxes.

For gnome-boxes guests the spice-vdagent package is needed for shared clipboards and automatic resizing of the guest desktop to fit the display window and spice-webdavd is needed for shared folders.

@{Buck Fankers}: yes, that's right. Just gnome-boxes and the spice packages should do it. MX-19 already has the spice-vdagent package (and I recently requested that they add spice-webdavd).
Thanks, will give it a try!

Thank you for all the info!

Paul..
You need to transform VirtualBox disks to KVM format.
I think you have to use the "vboxmanage" command..

I'd like to ditch Virtualbox and start enjoying KVM but I am facing some issues even for creating my first VM.
I get this error:
Code: Select all
could not start virtual network 'default': internal error: Failed to initialize a valid firewall backend
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/netlist.py", line 361, in validate_network
netobj.start()
File "/usr/share/virt-manager/virtManager/libvirtobject.py", line 83, in newfn
ret = fn(self, *args, **kwargs)
File "/usr/share/virt-manager/virtManager/network.py", line 81, in start
self._backend.create()

if ret == -1: raise libvirtError ('virNetworkCreate() failed', net=self)
libvirtError: internal error: Failed to initialize a valid firewall backend
I did a search on the web and found that some fixed it disabling ipv6 but I am not sure it is my case.
My pc is connected with wifi, not ethernet.
