Test case
======
146351: OP:System Stress_RAID1_Pegas 1.1_ZoemIO-24_KVM
ZoemIO24 = PM8069
For this test case, I created a raid1 in the KVM host using 2 SAS drives which are controlled by the PM8069 onboard sas/sata controller . I rebooted my machine to complete my set up for other test cases which I planned to run them together. I then passed this raid1 to a guest. In the guest, as soon as I su - to htx, these messages appeared on the SOL of the guest
As a side note. There was no error when raid1 was created and after I rebooted this machine

Without the previously mentioned patches, the system cannot pass a RAID volume on the primary disk controller to KVM guests.

Hi,
thank you for the report.
I have backported the fix (had only minimal backport noise) and I think it will be fine.
It is currently building in a ppa [1].
I'll run general regression tests on that at some point (I'm currently modifying the testbeds of those regressions so it might be a day or two to complete them).
Lacking most of the HW needed for this I wanted to ask you to explicitly verify the version in the PPA against your case and report here if it is good.
Once both tests are good we can upload it for Bionic.
It is a pure bug fix, so even if this worst case slips GA it can be converted to be an very early SRU.
