Description of problem:
Trying to test install RHEL 7.5 or CentOS 1804 in libvirt/qemu-kvm/virt-manager (as I always do - so this is a regression).
Boot ISO and moans:
'[INFO] dev-virtio\x2dports-com.redhat.spice.0.device is not active'
'[DEPEND] Dependency failed for Activation socket for spice guest agent daemon.'
If you go further into install to security policy section. Selection of 'Standard System Security Profile', fails with:
'/dev/shm must be on a separate partition or logical volume.'
Steps to Reproduce:
1. RHEL 7.5 host.
2. Create a RHEL 7.x guest in virt-manager.
3. Boot from ISO and see boot info/errors.
4. Go deeper into the install process and select 'Standard System Security Profile'.
Same as RHEL 7.4 or CentOS 1708 and get no issues.
Secondary issue with security profiles has been filed on bugzilla:
thus, this portion of the bug report can be ignored.
Thanks for the report. I'll close this as DUP, please follow the other bug.
