David_Dai: Am I correct to assume that the kernel panic you have shown did happen at the shutdown of TC? I'm using a lot of VMs (mostly QEMU and VBox) and on very few occasions I've seen a kernel panic at shutdown time (not limited to TC but IIRC also with Ubuntu, or Fedora).
I'm not too worried if that happens once in a while. In particular with TC I don't see an issue if it happens after the backup and syncing of all attached disks. Nevertheless it would be important to know whether you've observed the kernel panic once, or is it occuring frequently? With what sort of configuration in terms of devices (i.e. CD-ROM, disks, etc)? What are the activities leading up to that event?
Furthermore I rarely use the Microsoft product "Virtual PC" (i.e. v6.0.210.0 in my case) with Linux systems. This product (for obvious reasons) does not (and probably will never) "officially" support any Linux system. For starters (at least in my own findings) the mouse is a bit of an issue, plus there was no performance advantange when compared to VBox or QEMU (with KQEMU). OTOH those alternatives work very well with Linux guests, so I don't see a reason to find possible ways to resolve or identify work-arrounds for the deficiencies of "Virtual PC".
