Hello,
I face this problem and I am willing to provide a patch in order to have
a more informative message.
This, of course with our help. I am not quite certain.
First of all: What is the problem?
On a fresh Install (ArchLinux for me), if ever forget to install Qemu
and launch "virt-install" with "--type kvm", I get the message:
"Host does not support any virtualization options"
According to me, this message should be improved: if Qemu is not found,
this should be "Did not find Qemu, please install it".
As I searched, the message is generated by this piece of code:
https://github.com/virt-manager/virt-manager/blob/c92aade081687b19f5a60cd...
As I write now, I cant find the pice of code actually calling the
"quemu" binary. I think I should add a try/catch block there and Raise
the right Exception.
Would someone help me a bit?
virt-manager is not calling any qemu binaries at all. It just relies on
whatever capabilities libvirt presents. The reason for that is remote
access - just imagine you'd be installing a domain on a remote machine
and virt-manager (virt-install) would spawn your local qemu binary to
find out its capabilities. That would be flawed, wouldn't it.
I agree that the error message can be made better (just like 90% of
other messages of ours), but first things first. What's the output of
'virsh capabilities' (if you're giving any connection URI to
virt-install give it to virsh too).
