I tried two different CentOS 6 VMs. Both have the latest standard kernel (2.6.32-279.5.2.el6.x86_64). Both run perfectly fine on one of the other VMware hosts still running ESXi 4.1.0 build 702113. On build 800380, both display the GRUB menu alright but freeze immediately afterwards, emitting the message
PANIC: early exception 0d rip 10:ffffffff81038879 error 0 cr2 0
on the bottom of the virtual console. Both run perfectly fine again once I move them back to the host with the older ESXi build.
Two and a half new data points:
- The problem host has a Xeon E3-1270V2 processor while the one which runs the CentOS 6 guests fine has an E3-1230. I'm not sufficiently up to date with Intel processor types to tell whether this would make a difference.
- Another CentOS 6 VM with older kernel 2.6.32-220.7.1.el6.x86_64 does come up on the problem host. It does a panic blink (Caps Lock and Scroll Lock blinking in unison while the VM has the keyboard) but I get a working login prompt (I don't get any further because I don't have a logon for the machine) and I can shut it down normally by sending Ctrl-Alt-Del.
- (the half point, no idea if it matters) The CentOS 6 VMs which die with "PANIC: early exception 0d" do *not* do a panic blink.
So it would seem that something related to the problem was changed in the CentOS kernel between releases 2.6.32-220.7.1 and 2.6.32-279.5.2.
