[libvirt-users] How to tell if a hypervisor connection has died?

[Guido Winkelmann]

Hi,

What's the best way to tell if a virConnect object is not good to use anymore? 
(For example because the libvirtd on the other side crashed/has been stopped 
or because of some network failure)

When I try this, the first API call I do on a broken connection yields an 
error with error number 38 (VIR_ERR_SYSTEM_ERROR) and all subsequent calls 
yield an error number 1 (VIR_ERR_INTERNAL_ERROR). Both of those are really 
unhelpful and could mean just about anything...
