Re: -current as guest of VMWare2
HAH! This patch was posted by iedowse in response to one of MY POSTS and
it does EXACTLY what I described in my previous Email, point (2).
PLZ DO NOT BRING MY HOPES UP BY STATING THAT THERE IS ANOTHER PATCH
WHICH DOES SOMETHING DIFFERENT WHEN IT FACT IT DOES WHAT I ALREADY KNOW
I SHOULD DO K PLZ THX. :-)
(I'm just fooling around, thanks for the pointer anyway. :-))
Cheers,
Bosko

Re: -current as guest of VMWare2
Here is the patch from a previous posting that fixes the problem of
running FreeBSD -Current as a Guest OS under VMWare Workstation 3.0:
Someone mentioned on a list somewhere that vmware takes forever to
emulate the cmpxchg instruction, and that using the I386_CPU version
of atomic_cmpset_int() helps a lot. I noticed a major vmware slowdown
with -current sometime in September, so I tried avoiding the
cmpxchg's and things got much faster. Below is the patch I use
(using this outside vmware on SMP hardware is a bad idea :-).

Avoids using the "LCK" prefix, which VMWare emulates very, very slowly.

Chapman Jr. > [EMAIL PROTECTED] Raintree Network Services, Inc. > [EMAIL PROTECTED] FreeBSD Committer As I mentionned several times now in this thread, I am running VMWare 3.1.1 with a host OS being Windows2000 and a guest OS, -CURRENT. I am doing this on my laptop so that I can "trick" -CURRENT into playing with my PCMCIA network card that is not supported but that works when used through VMWare due to VMWare emulating a LANCE type (lnc) card. Here are the issue I ran into with -CURRENT as guest, and what I've done to solve them so far: 1) Issue: -CURRENT installation boots, kernel boots, sysinstall starts, but newfs-ing on partitions is EXTREMELY slow. Solution: Don't use the VMware 'virtual disk' thing backed with a file on the host OS. Instead, create a separate partition for FreeBSD and install there. Disk access is quite a bit faster. 2) Issue: sysinstall now can newfs easily/quickly, it starts the install on / first, but eventually slows down to a crawl (the rate sinks to something ridiculous, like 0.5K/s. Solution: Haven't figured it out yet. My plan is to: (i) Re-install -CURRENT snap in the separate partition but not through VMWare (i.e. do it the "normal" way). (ii) Boot -CURRENT normally (iii) Rebuild kernel without cmpxchg instruction (cpu I386_CPU, or whatever the name of that option was). (iv) Boot host OS windows2000, start VMWare, and try booting the installed -CURRENT with the new cmpxchg-free kernel via VMWare. I hope this at least improves the speed situation. -- Bosko Milekic [EMAIL PROTECTED] [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

-current as guest of VMWare2
Hi folks, I'm currently trying to install -current as a guest OS of VMWare2 running under 4.6RC. The problem is that it works correctly except that after some processing, the VMWare2 engine slows down the OS incredibly. To get things back to a correct speed I have to suspend the VMWare session then restore it. I also have a VMWare2 guest 4.6RC (running on the same 4.6RC host) which works like a charm. I've compiled with the following machine file: Any idea?
