Re: [Libvir] virDomainGetInfo returns a false result on IA64 systems
In Xen-unstable (future Xen 3.0.3), the page size has been added in the
"xm info" command:
xen_pagesize : 16384
I think that this big problem can't be easily resolved in libvirt while
Xen 3.0.3 isn't delivered.
Perhaps, a temporary solution would be to consider page size as 16 KB on
IA64 ?
Philippe Berthault a écrit :
The maxMem and memory fields of the virDomainInfo structure are false
on IA64 systems.
The problem is in xen_internal.c at lines 1530,1531:
info->memory = XEN_GETDOMAININFO_TOT_PAGES(dominfo) * 4;
info->maxMem = XEN_GETDOMAININFO_MAX_PAGES(dominfo) * 4;
It's assumed that page size is 4 KB (* 4) but this isn't correct on a
IA64 system where the page size is variable.
I haven't checked but I suppose this bug exists also with the
virDomainGetMaxMemory and virDomainSetMaxMemory functions.
Regards.
