Hi All,
I'm new to Xen world and am in the process of collecting performance information of various guests from dom0. Can somebody help me out with these problems.

1. I downloaded libvirt-0.3.3 src and did a 'make' and I'm seeing this problem.

xen_internal.c: In function 'xenHypervisorDomainGetOSType':
xen_internal.c:2711: error: 'DOMFLAGS_HVM' undeclared (first use in this function)
xen_internal.c:2711: error: (Each undeclared identifier is reported only once
xen_internal.c:2711: error: for each function it appears in.)
xen_internal.c: In function 'xenHypervisorGetDomInfo':
xen_internal.c:2943: error: 'DOMFLAGS_HVM' undeclared (first use in this function)
make[2]: *** [libvirt_la-xen_internal.lo] Error 1

2. I want to know what are the rpm that the Xen server must have to pull out the performance data of various guests.

3. My Xen server now has these rpms :
 # rpm -qa |grep libvirt
        libvirt-0.2.0-0.16
        libvirt-python-0.2.0-0.16

Do I need any other rpms to compile my c programs ? Is there any document which says how I can compile my c-program using libvirt ? I tried running info1 example in debug mode and I get this error :

./info1

libvir: Xen Store error : could not use Xen hypervisor entry failed to connect to Xen Store
libvirt: xenUnifiedOpen: Xen sub-driver 3 open failed
libvirt: do_open: driver 2 Xen returned ERROR
Failed to connect to hypervisor

4. what is libvirt_proxy ? What is its use ?
I assume this is used to connect to hypervisor (am I right ?) When I run this, it says "Failed to open Xen hypervisor"

Is there any document which can give more details of all these details ?
Any help will be greatly helpful

Thanks,
