I just imported a Solaris 10 u8 VM into Vbox 3.1.0 on a WinXP x64 host. The host has 4GB ram and a quad-core Xeon E5120 processor. The guest VM was made on a WinXP 32-bit host, and exported in ovf format. On the new x64 host, I am running the guest in 64-bit mode with VT-x enabled. When I boot the guest, I get this error:
WARNING: cpu0 failed to update microcode form version 0x0 to 0xcb.
If select one processor for the VM, I get the error once. If I select two processors, I get the error twice, with the second instance referencing cpu1. Is this normal? Besides the fact that my guest display will NOT resize automatically to fit the 1280x1024 display as it usually does, the guest seems to be running normally.
