Hi OVM folks,
I had a 3.2.9 Manager with one pool of six servers. I did an upgrade of manager to 3.3.1 and then I started with the first server with UpgradeServers.py. It prepared new rpms on the server and then it rebooted it. The server should boot into the new kernel i.e. 3.8.13-26.4.2.el6uek, but the boot fails after "scrubbing free ram". I tried to search anything about it with google string
reboot after "scrubbing free ram"
There was plenty discussions about "xen dom0 reboot after scrubbing free ram", but nothing understandable and helpful for my case. I tried to modify its grub line
kernel /xen.gz dom0_mem=2440M
as these:
kernel /xen.gz dom0_mem=2440M iommu_inclusive_mapping
kernel /xen.gz dom0_mem=2440M iommu_inclusive_mapping=y
kernel /xen.gz dom0_mem=2440M iommu_inclusive_mapping=1
kernel /xen.gz dom0_mem=2440M iommu=passtrough iommu_inclusive_mapping=1
kernel /xen.gz dom0_mem=2440M iommu=1 iommu_inclusive_mapping=1
kernel /xen.gz dom0_mem=2440M allowsuperpage
kernel /xen.gz allowsuperpage dom0_mem=2440M
kernel /xen.gz dom0_mem=2440M allowsuperpage iommu_inclusive_mapping
kernel /xen.gz allowsuperpage dom0_mem=2440M no-bootscrub
kernel /xen.gz dom0_mem=2440M iommu=no
kernel /xen.gz dom0_mem=2440M iommu=verbose
but in all cases it does "scrubbing free ram", then blank black screen and then next boot of the server as it was reset. This servers is ProLiant DL380 G7 with 143.99 GiB of memory.
Please, do anybody has any idea what to try?
with hope
Tom
