[ovirt-users] missing hvc0 device on hosted engine

[Martin Sivak]

Hi,

we know about this and we already pushed patches that should resolve
this issue in 4.1.1 (one was merged today in fact).

We track the issue here:
https://bugzilla.redhat.com/show_bug.cgi?id=1364132 and the patch that
should resolve it is here: https://gerrit.ovirt.org/#/c/71472/

Applying the change manually or waiting for a new snapshot package in
http://resources.ovirt.org/pub/ovirt-4.1-snapshot/rpm/<distro>/noarch/
might help you in the meantime.

Best regards
