A solution for guest os's freezing on Fedora 10 64bit.
Posted: 6. Feb 2009, 17:44
Recently had lockups occurring with Windows XP Pro SP 2 and Fedora 10 32 bit guests.
The Windows XP guest would freeze and seconds later another concurrent guest ( 32 bit Fedora 10 ) would freeze. Followed by host mouse becoming increasing unresponsive to the point of not usable, requiring a complete reboot.
This was puzzling as recently all was working well without incident. So in considering what had changed from the working to the non working case I realized I had turned the Wireless enable/disable switch on laptop to off. If the gnome network manager hasn't had wireless disabled then the linux guest would lock up during boot in this case.
Turning wireless enable switch back on and with network manager having wireless network enabled, neither guest has locked up for hours whereas before would reliably freeze up all guests within 5 minutes of startup.
Once the freezing issue seemed sorted I then moved on to getting virtual box to make use of the built in cpu virtualization by setting the Enable VT-x option on both clients and all seems well. No more freezes and system reboots. It also seems that the guest os's are far more responsive. Applications that were taking several minutes to load now load in 15 seconds.
