(common/util/HmclDrmgrHelper.cpp:1036) Command /usr/sbin/pvmdrmgr drmgr -c slot 
-s 'U9080.MHE.218BA37-V1-C8' -r -w 3 returned 255. Additional messages: 
/usr/sbin/pvmdrmgr drmgr -c slot -s 'U9080.MHE.218BA37-V1-C8' -r -w 3
Validating I/O DLPAR capability...yes.
failed to open /sys/bus/pci/slots/U9080.MHE.218BA37-V1-C8/power: No such file 
or directory
failed to disable hotplug children
Isolation failed for 30000008 with -9001
Valid outstanding translations exist.

---Steps to Reproduce---
 Create a VM from PowerVC on a Novalink managed host. Unmanage and manage the 
VM, this problem gets reproduced
 
==
I've tested a proposed fix and it does fix both the -9001 isolation errors 
after DLPAR remove and vterm state is still open, as well as the /dev/hcvsX 
index changing after a DLPAR remove/add. I will get that patch sent out to the 
upstream mailing list for merging.
