The KVM smoke test failed on P8 systems with Bionic kernel.

But the test can pass if you run it by hand, it looks like the wait command needs some time to wait for the KVM to boot.

Maybe we should check this first by adding some sleep command.

Tested with P8 "modoc" + Bionic 4.18 kernel

It won't pass the test and still return:
uvt-kvm: error: libvirt domain 'bjf-test' is not running.

[Po-Hsu Lin (cypressyew)]

The error on Eoan 5.3 P8 (node modoc) is:

  uvt-kvm create bjf-test release=eoan arch=ppc64el
  uvt-kvm: error: libvirt: internal error: qemu unexpectedly closed the monitor: 2019-10-26T22:05:58.048240Z qemu-system-ppc64le: Requested safe cache capability level not supported by kvm, try cap-cfpc=broken
  uvt-kvm wait bjf-test --insecure --ssh-private-key-file /home/ubuntu/.ssh/id_rsa
  uvt-kvm: error: libvirt: Domain not found: no domain with matching name 'bjf-test'

[Po-Hsu Lin (cypressyew)]

BTW this test has passed on the P9 node baltar with the same Eoan kernel.

[Po-Hsu Lin (cypressyew)]

P8 (node dryden) works with B-4.15 and F-5.4.
G-5.8 failed with bug 1930646

I think we can close this bug now.
