I'm running Oracle Linux 6.3 on a VMware machine which based on a HP Proliant BL620c G7 server.
I've installed IBM Websphere version 8.5 and IBM HTTP Server version 8.5.
After installing VMware tools for this machine, I was asked to reboot the server, but on start we got a kernel panic such as below:
It looks like the system has trouble opening or finding the /boot volume. I don't think it is an incompatibility with your hardware. You might however want to make sure you installed a recent VMware version and have correct settings to support x64 guest OS. I'm not using VMware anymore, but under VirtualBox such issue can be due to missing I/O apic and VT-x support in the BIOS.
