Re: [Libvir] [PATCH] Fix the value of XEN_V2_OP_GETDOMAININFOLIST

Hi,
The value of "Max memory" shown by using "virsh dominfo" is different
from xm
command.
# virsh dominfo HVM_RH5_sda6 | grep mem
Max memory: 300000 kB
Used memory: 264064 kB
# xm li -l HVM_RH5_sda6 | grep mem
(maxmem 450)
(memory 292)
(shadow_memory 5)
So, I changed the definition as follows,
(before)
#define XEN_V2_OP_GETDOMAININFOLIST 6
(changed)
#define XEN_V2_OP_GETDOMAININFOLIST 5
and I could get the value that I want.
This doesn't make any sense to me.
There are two hypercalls in the Xen headers, XEN_SYSCTL_getdomaininfolist
and XEN_DOMCTL_getdomaininfo, which use the same struct. The former gets
info on multiple domains, the latter on a single domain. In the libvirt
code we always use the sysctl even when getting info for a single domain.
So XEN_V2_OP_GETDOMAININFOLIST should match XEN_SYSCTL_getdomaininfolist,
which AFAICT we already have correct.
Does this problem occurr for you on all architectures ? Also what version
number of xen & libvirt have you got installed ?

Dan.
