Re: [Xen-users] Dom0 memory not accepted

Hi,

a litte addendum to the xl info - there are already vms running, so the shown 
free mem isn't r4eally free, it's already used by vms


xl list
Name                                        ID   Mem VCPUs      State   Time(s)

here it shows the 4G available, and if I do:

 xl mem-set Domain-0 4g
 xl list
Name                                        ID   Mem VCPUs      State   Time(s)

and xentop shows

      NAME  STATE   CPU(sec) CPU(%)     MEM(k) MEM(%)  MAXMEM(k) MAXMEM(%)

that works all mem is used - where is the problem with the initial setting via 
xen-cmdline ?

Or should I direct that issue to another list or the debian maintainers 
directly ?
