Hello everyone!
I have this doubt:
Well, i have a my server with xen 3.0.2 and 4GB on RAM, i want to create on this
server only one virtual machine.
So, what''s the maximum amount of RAM that can i give to my VM?? (Having
in mind that my Dom0 only has 4GB :P)
Thanks in advance.
Hope somebody help me with this.
Regards
Ivan

How much memory you require for your Dom0 depends upon whether you run any applications on dom0 or not. If you don''t run any workload on Dom0 (which is recommended from a security POV), 256 MB of memory would be more than enough for Dom0 to function normally and you can allocate the rest of the memory to Domu. --Sadique> > Thanks in advance. > Hope somebody help me with this. > > Regards > Ivan > > > > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
