[Leaplist] Suggestion for Virtualizing Server software

[tonyb]

Here is my experience:

Xen worked fairly well under openSuse 10.2.  It has some problems
allocating kernel memory for pci cards under openSuse 10.3 but I believe
that the latest kernel fixes that problem.  If you are using Xen with a
nvidia graphics card and regardless of which os you use you will have to
jump through hoops to get accelerated graphics to work with a dual-head
setup.

I tend to set things up and not experiment with my main machine too much
so I won't get back to Xen/nvidia/dual-head until openSuse 11.

I'm using vmware server, which is a free download, on SLES 10.1 at work.
 It has few more features than Xen but I discovered a problem.  When you
click in the vmware window it locks the mouse to that window which is
normal operation.  During the install of a SLES 10.1 virtual machine I
could repeatably crash vmware by moving the mouse within the vmware
window.  Once the virtual machine was install this problem has not
manifest itself.  Now for the thing that really bothered me.  When I was
googling the problem it found a link to the vmware community site.  I
clicked on the link and the page had been removed from the vmware site.
 I was able to read the google cache link and learn that others were
having the same problem.  Of course I can't find the dead link now but
this kind of stuff is disturbing.  Vmware also hangs and/or crashes when
dual-processor support is turned on.  Also keep in mind that the free
vmware server provides what Xen calls "para-virtualization".  This means
that vmware server is not as efficient as Xen.  Now that I have vmware
working, I do find it useful but I have every intention of revisiting
Xen when I have a chance.

I hope this helps.  YMMV.
