Hi,
Thanks for the response. So after a little more digging, I find this in the
xend error log
[2011-03-02 12:24:51 xend.XendDomainInfo 4324] ERROR (XendDomainInfo:219)
Domain construction failed
Traceback (most recent call last):

hvm = hvm)
Error: (12, ''Cannot allocate memory'')
Strange thing is that Dom0 has loads of memory free, as does the box. What I
do find interesting is that the box is currently using 32GB of RAM .. I read
somewhere that Xen only recognizes 32GB?

Subject: Re: [Xen-users] Max Number of Domains
Try this.

4.4. When I start a 9th domain using a loop-back file as its virtual disk
why do I get "Error: vbd: Segment not found:
uname=file:/path/to/image"?
By default, Linux only allows up to 8 loop-back devices to be active. You
can increase this number by setting max_loop=32 (etc) on the domain 0 kernel
command line in Grub. You also need to create new loop[n] device nodes in
/dev.

I am having a problem starting the 41st domain on a host of mine. It simply
will not start, but when I shut down an existing one, then it will boot up
fine, so there appears to be a limit on the number that can run at a time.
Im running xen 3.2 currently.
Any ideas?
