This sounds like a bug in Xen, rather than a bug in libvirt - we don't
have any special handling for Domain-0 - we're just passing back through
whatever data we get from Xen.
Dan.
This problem seems to be caused by a missing initialization (in Xen or
libvirt ? to be determined) because after setting the system memory size
by using the "xm mem-max" command on Domain-0, the Max memory value
returned by virsh is correct and reflect the value passed to the xm command.
This problem of incoherent maxMem value on Domain-0 has been detected
after a system reboot.
