[Xen-users] memory problem, possible bug in testing

[Harald Schioeberg <schioebe@xxxxxxxxxxxxx>]

Hello, i have this problem:

Hawaii0 xen # xm create Hawaii1
Using config file "Hawaii1".
Error: I need 129 MiB, but dom0_min_mem is 128 and shrinking to 128 MiB
would leave only 68 MiB free.

But I really have enough memory.
