The documentation of libvirt doesn't indicate which functions are for Xen or QEMU or both. The only way to know that, is by searching in libvirt sources.It would be interesting for libvirt users to add in the documentation, for each function, a mention such as "QEMU only", "Xen(TM) only", "QEMU and Xen(TM)", etc..
Thanks for looking into this.
Regards. Libvirt 0.2.3 functions dedicated to QEMU only: virConnectListDefinedNetworks virConnectListNetworks virConnectNumOfDefinedNetworks virConnectNumOfNetworks
The above should work on Xen too ...
virNetworkCreate virNetworkCreateXML virNetworkDefineXML virNetworkDestroy virNetworkFree virNetworkGetAutostart virNetworkGetBridgeName virNetworkGetName virNetworkGetUUID virNetworkGetUUIDString virNetworkGetXMLDesc virNetworkLookupByName virNetworkLookupByUUID virNetworkLookupByUUIDString virNetworkSetAutostart virNetworkUndefine
The network functions currently use the QEMU server. That's a strange historical artifact that should be removed (or perhaps has been by Dan's patches - I have yet to check them in detail).
Libvirt 0.2.3 functions dedicated to Xen(TM) only: virConnectGetMaxVcpus virConnectGetType virDomainAttachDevice virDomainCoreDump virDomainDetachDevice virDomainGetMaxMemory virDomainGetSchedulerParameters virDomainGetSchedulerType virDomainPinVcpu virDomainReboot virDomainSetMaxMemory virDomainSetMemory virDomainSetSchedulerParameters virDomainSetVcpus
A lot of these are Xen-specific features. Some may one day be supported by kvm when it gets proper, working SMP support. I notice they got an SMP guest to boot a couple of weeks ago. However virConnectGetType should work on QEMU.
