Thanks for your assistance. Tried it, but still makes no difference.

Subject: Re: [Xen-API] xcp and minimum memory 


1) don't use xend (or it configs). xapi or xend, not both. 
2) Proper setting is 

/etc/default/grub 
# Start dom0 with less RAM 
GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=1024M" 

and do update-grub after changing default.

Hi, 


I've installed xcp (xcp-xapi) on Ubuntu 12.04 - installed, but have gotten no 
further. What's stopped me dead in my tracks is that Xen appears to grab most 
of my 6GB of memory - well, *something does* - leaving only 1GB for me to run 
my desktop on. Very slow and painful to use. (It would be ideal to run this on 
a test server, but nothing is available.) 


First, do I understand correctly that "dom0" is just the host system? In other 
words, when I boot the Xen kernel, that's dom0, yes? 


Here's what I've tried up to this point. 




Edited /etc/default/grub 

GRUB_CMDLINE_XEN="dom0_mem=2G,max:2G" 

also tried 

GRUB_CMDLINE_XEN="dom0_mem=512M,max:512M" 




... followed by update-grub command. 




Edited /etc/xen/xend-config.sxp 

-------------------------------------- 

xend-config.sxp:(dom0-min-mem 2048) 

(enable-dom0-ballooning no) 


All mods followed by reboots, of course. None seems to make any difference. The 
performance monitor application and "free" command show just under 1GB 
available when booted under the Xen kernel, 6BG when booted under normal 
Ubuntu. 

Xen reports the proper memory stats: 


# xe host-list params=all | grep memory 

memory-overhead ( RO): 83017728 

memory-total ( RO): 6372888576 

memory-free ( RO): 5120520192 

memory-free-computed ( RO): <expensive field> 




Have I missed some basic concept somewhere? Anyone have similar problems? 




Cheers, 

Lyn
