Red Hat Bugzilla – Bug 170985
RHEL 4 Update 2 Incompatibility with VMware ESX 2.5.2
Last modified: 2007-11-30 17:07:21 EST
- VMware ESX build 16390 (latest version on 2005-10-16)
- running on a HP Proliant Server P3 host with single CPU w/ SCSI disk
- RHEL 4 Update 2 iso files.
When booting a guest machine with the Update 2 iso file the kernel crash while
loading one of the SCSI module.
If a guest machine is installed with Update 1 it work fine until it's up2date'd
to match "Update 2" package versions and kernel upgraded to 2.6.9-22.EL.
It crashed at next reboot and require a fall back to 2.6.9-11.EL kernel.
I found this message on nahant-beta-list that look like my problem:
Someone else seem to had reproduce this problem before with Update 2-beta.
I am investigating the nahant-beta-list posting to see what became of it.
In the meantime, please post the console messages that print when the system
I found out about this bug today the hard way. Last section of console screen
before VM poweroff:
"Uncompressing Linux... Ok, booting the kernel.
PCI: Cannot allocate resource region 4 of device 0000:00:07.1
Red Hat nash version 184.108.40.206 starting
sda: assuming drive cache: write through"
System boots fine going back to 2.6.9-11.
There is more detail of this problem on the vmware forums. It seems that the
latest mptscsi driver does a target reset on unused targets. The real hardware
doesn't support this, and the vmware emulation dies when this happens.
There is also a patch on the vmware forums that fixes this, it would be nice for
that to get into the distribution kernels.
See http://www.vmware.com/community/thread.jspa?messageID=306923 for more details!
We should have something like that already. Could you try this kernel?
http://people.redhat.com/~jbaron/rhel4/RPMS.kernel/ These are experimental kernels.
Thanks, I've tried the smp version of that kernel and it seems to work fine.
I take it kernels like these will end up in the next update?
Thanks for testing. Yeah, U3.
