virtualbox guest EXTREMELY slow after upgrade(s)

after returning from a trip (5/21 - 5/30) i upgraded my system as usual via pacman -Syu.   since then my host machine (arch-64) runs fine, network is fine, etc., but my xp system which runs via virtualbox has been incredibly slow.  i.e.  35 minutes to finish booting instead of a few, and, once up, doing something like starting IE and navigating to a web site takes another 4-5 minutes to fully complete.

does anyone know what is causing this?  my VB version (4.08) seems current.  nothing has a virus.  there is nothing wrong with my network connection, router, or anything else like that.

Re: virtualbox guest EXTREMELY slow after upgrade(s)

Sounds like the virtual machine's "Enable VT-x" system option has been switched off.

Another thing to check: If you've upgraded the kernel, recompile the virtualbox kernel modules.

Re: virtualbox guest EXTREMELY slow after upgrade(s)

nope.  all the same options are still enabled, and i always recompile the kernel modules after every arch kernel update.  it is something else; the change is so marked that i assume it has to be related to the linux kernel (though of course i am sufficiently unsure that i posted the question).

does no one else observe this?

Windows 7 x64 guest boots just fine within a couple of seconds here.

Re: virtualbox guest EXTREMELY slow after upgrade(s)

@djg1971: Hi, I'm a Fedora user (Fedora 15 + KDE) and I had the same issue you're mentioning when updating Vbox from 4.0.6 to 4.0.8,
I actually posted my situation in the VirtualBox Forums:

http://forums.virtualbox.org/viewtopic.php?f=7&t=42225

And it seems some Windows users are experiencing this too:

http://forums.virtualbox.org/viewtopic.php?f=6&p=189058

In my case, I also thought it might be a Virus or something like that
because my host machine was very very slow and CPU was always at 100%,
But it turned out the system was clean and with a perfect performance without the VM...

(The VM used to crash a lot with no reason also, This never happened before)

The solution for me was Downgrading from VirtualBox 4.0.8 to VirtualBox 4.0.6, (Both the Software and the EXTPack)
Now everything works as it used to work in both the host an the guest O.S. (pretty fast)

Hope someone can explain this to us...

Re: virtualbox guest EXTREMELY slow after upgrade(s)

I'm running arch64 and I'm having issues in virtualbox with the latest kernel. My XP VM doesn't start, the progress bar stay freeze and after that I can't halt my system properly. Very odd... with kernel lts everything works fine. I'm trying to understand this issue better...

Re: virtualbox guest EXTREMELY slow after upgrade(s)

I'm having the same issue here. Virtual machines hang on startup. I'm not sure when it started as I haven't used virtualbox in a couple of weeks. I'll try downgrading when I get the time and see if that fixes it.
