Re: [Qemu-discuss] [Solved] Installed Ubuntu 14.04 and now getting "unknown OS type hvm" on my old VMs. |

Greetings,
I solved the problem. The solution is embarrassing; Qemu and KVM were
not installed. I assumed (wrongly) that by installing the 'libvirt-bin'
package, the other packages would install as dependencies but I was
wrong. What mislead me is that many directories with 'qemu' in their
names are created when installing 'libvirt-bin', such as
'/etc/libvirt/qemu', giving the false impression that everything is
there. It is by using the GUI (virt-manager) instead of the CLI (virsh)
that I got an error stating that Qemu was not installed.
If any libvirt developer is reading this, a better error message would
be appreciated. Something like "No virtual manager installed. Please
install one such as Qemu." would be appreciated.
I send my Thanks to Jakob Bohm and Ziemowit Pierzycki for answering my
original email.
Best regards,
Hans Deragon
