The maxMem field of the virDomainInfo structure is given in bytes instead of Kbytes when the domain is 0 (Domain-0). With others domains, the value of maxMem is correct.
Exemple with virsh: On a system with 4 GB memory, virsh reports: # virsh dominfo 0 ... Max memory: 4294967292 kB
With the same libvirt version 0.1.9 but with an older Xen (not 3.0.3), the maxMem value of Domain-0 is correct.
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.
