Re: Where to get FreeBSD port for Xen

It looks like apache had gone out to lunch. I just restarted it and it
is accessible again. If you wait a day I'll have 5.3 up. 5.2.1 is what
is there right now.

Long term, yes. But unless someone else decides to help out, it probably
won't be this year.

Kip:

Any luck with that FreeBSD 5.3 kernel? Our network engineer wants to set 
up a Xen box for internal use with Debian and FreeBSD on it, and I'm 
hoping to get FreeBSD 5.3 on there. Also, were you able to figure out 
the blocking stuff in the scheduling code?

It is up and working I just wanted to create a smaller loopback root and
do some more xen work before posting. I guess I can post it in an hour
or so.

Yeah, I was just hoping for a more attractive interface to managing
that.

Okie Dokie. Check out:
http://www.fsmware.com/xenofreebsd/5.3/
It only has the kernel, a compressed mdroot, and the config scripts
that I use. The blocking issue discussed previously has not been fixed.
I intend to fix it, but there are some infrastructure bits that take
priority for me.

Let me know how this works for you as soon as you try it out.

Bad news, I'm afraid; the 5.3 kernel and mdroot doesn't successfully 
boot for me. I'm using the same args that happily boot the 5.2.1 kernel, 
but it simply stops once it reaches a certain point. The boot messages 
are as follows:

I'm using the following config:

kernel = "/boot/freebsd-5.3-xenU"
memory = 128
cpu = -1
name = "freebsd"
nics = 1
vif = [ 'mac=aa:00:00:00:00:28,bridge=xen-br0' ]
disk = [ 'file:/var/local/freebsd.image,loop0,w' ]
extra = "boot.netif.ip=192.168.0.33"
extra += ",boot.netif.netmask=255.255.255.0"
extra += ",boot.netif.gateway=192.168.0.1"
extra += ",vfs.root.mountfrom=ufs:/dev/xbd0a"
extra += ",boot_verbose=yes"

And I am using the 'mdroot' that you posted with the kernel; however, 
based on the boot messages, it doesn't even look like it's getting far 
enough for that to be an issue. I was also able to build a FreeBSD/Xen 
5.3 kernel, but I'm encountering the same issue, at the same point in 
the boot process.

It is getting late and the 2.0-testing snapshot I'm running just locked
up on me. I'll look at it further tomorrow.

Could you try looking at my freebsd config file? I didn't partition this
mdroot the same way as I did the previous one. That may somehow be
giving you grief.

It seems to be related to the host system. I tried booting your FreeBSD 
5.3 kernel and mdroot on a P4 Celeron system here in my office running 
Xen (2.0.1, fyi); the kernel fired right up, mounted root, and came to a 
login: prompt. The system that was having problems is a dual Opteron 242 
with 1 GB of RAM (it's an HP DL145, specifically).

If you'd like to log into the machine directly and see if you can figure 
anything out, please contact me off-list, and we'll make arrangements; 
I'd like to see this work, but obviously the not-booting thing is kind 
of a downer. :)

Interesting. My test machines are all, with the exception of an old dual
PIII from Dell, dual Opteron 242s from Penguin Computing.

Will follow up.

Well dandy. I've modified my config to mirror yours _exactly_ and it
boots just fine. So make sure you're running the latest 2.0-testing
snapshot follow up with me when you the chance.

OpenBSD port for Xen

[Dave Feustel]

Is there any chance of this or should I just wait for
Intel's Vanderpool or AMD's equivalent?

It is a chunk of work. You have to heavily modify pmap.c, replace all
privileged operations with the corresponding xen operations, and port
over the clock, block, and network device drivers.

Re: Re: OpenBSD port for Xen

[Scott Parish]

Looked briefly: openbsd and netbsd have already diverged enough that
applying patches from netbsd xen wasn't going to be quite trivial.

I just went ahead and got the xen-2.0-testing tarball, and build the 
hypervisor and userspace utilities. After restarting, I tried starting 
the FreeBSD kernel inside a Xen domain; the result is currently the 
same. I'll check the BIOS settings and see if, perhaps, there's 
something relevant, but at this point, I'm still guessing it's something 
about this machine. I'm not sure what though.

Thank you very much for your work, Kip.

I successfully booted xenofreebsd from your source.
The following patch(obtained from NetBSD) seems to
fix the scheduling problem.

Thanks for patch and the heads up on the successful boot.

I'll apply the patch and update the posted tarball and kernel tonight.

Re: Re: Where to get FreeBSD port for Xen

[Hidetoshi Shimokawa]

I have experianced strange lockups sometimes.
In that case, 'xm list' shows no state for freebsd.
(usually it is blocked)

Name              Id  Mem(MB)  CPU  State  Time(s)  Console
Domain-0           0       59    0  r----    990.1        
freebsd.sample     2       64    0  -----    547.6    9602

I'd like to analyze this problem using debugger.
I found gdbserver binary in your web site but it seems old and
to require old libraries. Can I get the gdbserver source?

Thanks,

Re: Re: Where to get FreeBSD port for Xen

[Kip Macy]

Funny you should ask. I just updated libxc to work with xen's current
context representation (previously I could just copy cpu_ctxt out and
everything worked, but just prior to the change most of the register
contents were wrong). I'll try to get everything posted within the hour.

One observation - I can't comment on 64MB, but FreeBSD 5.x doesn't do an
adequate job of managing its memory to stay up with 32MB or less.
