Hi,

I've just installed vSphere 4.1 on an HP ProLiant ML115 G5 Quad-core and am trying to install CentOS 5.5 as a guest system.

However, when the guest boots up I get a calibrate_APIC_clock warning and a kernel panic message.

I've come across this knowledge base article on the vmware website which suggests moving the guest onto another Intel based host (!). Funnily enough I don't have a collection of spare host servers sitting around, so can anyone suggest another solution?

Alternatively, would installing an earlier version of CentOS get around this issue, or would a yum update put me back to square one?

How about BIOS settings, could anything be tweaked there?

Thanks.
