I'm sorry for my delay in replying. I made a mistake when I confirmed
this problem before.

I said I could get the value after I changed the definition of 
XEN_V2_OP_GETDOMAININFOLIST.
But actually the virsh command showed the value using "xend_internal.c",
not using "xen_internal.c".

Here is a result of a comparing between "xend_internal.c" and "xen_internal.c".

# xm list
Name                                      ID   Mem VCPUs      State   Time(s)
Domain-0                                   0   729     2     r-----    483.5
HVM_RH5_sda6                               5   195     2     ------  10294.2

# virsh setmaxmem HVM_RH5_sda6 500000

# xm list -l HVM_RH5_sda6 | grep mem
    (maxmem 400)
    (memory 195)
    (shadow_memory 6)

# ./virsh dominfo HVM_RH5_sda6
[DEBUG] using: xenDaemonDomainGetInfo

# ./virsh dominfo HVM_RH5_sda6
[DEBUG] using: xenHypervisorGetDomainInfo

I think the value is correct when using "xenDaemonDomainGetInfo".
So I want to use only "xenDaemonDomainGetInfo" for Xen when executing 
"virsh dominfo" command. How does that sound ?

Thanks,
Saori Fukuta
