Hello, I''m struggling to handle the amount of memory that dom0 gets on some system. It''s a system with 8GB of RAM, running 2.6.38-6 with pv_ops and Xen 4.1 If I want to set the amount of memory for dom0, I get very bogus results. See here: http://pastebin.com/gRgY9ERN If I use the M notation (xl mem-set 0 4096M) the outcome is similarily unpredictable, and sometimes I get the memory set to something like 200-300MB and in rare cases a kernel panic. Also, if I set the "dom0_mem=X" kernel parameter, the amount of memory Xen gives to dom0 is fairly random... sometimes 2GB, sometimes 6GB, sometimes ~500MB, regrardless of what value I use or the unit I use (M or no unit, for the default KB). Anyone else has experienced this in Xen 4.1? Thanks! _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Hi Claudiu, Xen 4.1.0 stable from the tar archive running on CentOS 5.6 with Jeremy''s 2.6.32.x kernel seems rock solid for me. I boot with dom0_mem=512M and get domain 0 with bang on 512MB of ram allocated. Just tried ammending the line to 1024M and have domain-0 booted with 1024MB of ram. Name ID Mem VCPUs State Time(s) Domain-0 0 1024 2 r----- 15.9 Iain On 18 May 2011, at 16:22, Claudiu Curcă wrote:> Hello, > > I''m struggling to handle the amount of memory that dom0 gets on some system. > > It''s a system with 8GB of RAM, running 2.6.38-6 with pv_ops and Xen 4.1 > If I want to set the amount of memory for dom0, I get very bogus > results.

Yes, I am. Using the old xm stack works fine, though... xm mem-set 0 <mem> sets the memory just fine... it''s xl who''s failing. However, the dom0_mem boot parameter still doesn''t work properly.
