FreeBSD completely broken with hardware virtualization enabled

[fzzzt]

I had FreeBSD 7 somewhat working in 1.6.4, but after moving to 2.0 (and then 2.0.2) it seems to be completely broken. Like, badly--BUT--only when hardware virtualization is enabled. With HV turned off, it seems to run okay (I installed and booted from disk just fine with HV off). Unfortunately I can't run two VMs this way. :(

When you boot (after installing with HV off) or try to install, the same thing happens. The screen constantly gets flooded with "BTX halted" messages (too fast for me to read them). I will attach a screenshot and the log file; hopefully one or both will be visible and useful.

Oh, a couple things I didn't mention:

1. On the bright side though, with HV off and the VM running I finally have low CPU usage (which never happened in 1.6). :)

2. I tried every combination of I/O APIC, ACPI and HV (FreeBSD is sometimes really picky about ACPI) but nothing helped, other than turning HV off.

3. FreeBSD 7.0 gave me the same results.

I can confirm the exact same problem. I have Guest FreeBsd 7.0 / Host Vista Sp1 The system is Intel Core2Duo

It was last runnig fine (with VT-x) on VBox 1.6.6 It fails on both 2.0.0. and 2.0.2 (same BTX halted)

I can confirm the same problem on Ubuntu Hardy host. VirtualBox 2.0.2.

I can confirm the same problem on Debian Lenny host, Virtualbox 2.0.4.

The same problem occurs in Virtualbox 2.0.6 (Host: Ubuntu 8.04.01 64-bit)

Is there any idea / inside knowledge which priority this bug has? or when a solution can be expected? I am aware this can not exactly be predicted, but at least things like "its top prior" or "there are 20 other bugs that go first" could be used to indicate a lead time?

Well, done (except for the fact that if you do not wish to give feedback: say so. Do not just ignore people who ask, please).

Anyway, I am going to provide feedback:

I have tested this Issue under VBox 2.1 with FreeBSd 6.2 and 7.0. Both went past he bootloader with no problem at all. (With VT-x enabled and with VT-x disabled).

So it does seem you fixed this bug.

FreeBsd 6.2 (that's the one your documentation says to have problems) booted all the way through and I can login and run applications. (I haven't checked for the SigReturn issue...)

FreeBSd 7.0 loads the kernal and dies at a later boot stage (separate bug report will be filled on this)

Thanks a lot.

Thanks for the feedback. The problem described here is solved then.
