Connecting to VirtualBox keeps Failing?
Hi,
I need to use VIrtualBox instead of the VirtualPC because the OS type I want is on the VirtualBox. I've debug this in the past, had this problem in the past but kernel / resync fixed it. this time it does nothing. Interesting, even though it says it's not connected, I can hit break and it breaks, but stays in waiting to connect so the VM is now dead, and the windbg doesn't do anything. So frustrating!! Any ideas? Is there any cache to clear or something like that (it was weird when I switch over from VirtualPC to VirtualBox using the same windbg setup, it reverted to something I used in the past for that machine).

are you boot debugging if not do bcdedit set /bootdebugging off on
the target machine
and windbg version 6.12 is tooo tooo old please upgrade windbg to
something newer than 6.12
I deleted all the workspaces and now it's working again. I have to use the older version so registers show up, the newer versions it's blank. On Win7 x64.
