I've got an ESXI that's been running for almost 3 years fine. Yesterday, I upgraded the machine's bios, installed RAM and 2 additional hard drives. Today I added a Windows VM and changed the Gateway, Subnet Mask, and IPs. Everything was going well. A couple hours ago I started installing Windows patches on the VM. But then I couldn't access the machine.
The tech at the colo facility took a look and said it was at the normal ESXi screen but, "The graphics are artifacting and displaying some weird red lines running top to bottom on the screen". I had the tech reboot the server.
When it rebooted, we got:
"Cannot set up ramdisk: boot image is corrupted"
[then some error codes]
"Visor tar header is invalid for var/lib/register/providerRegister
No place on disk to dump data and after that it has the line that it is waiting for debugger"
What should I do now?
