Hi, I have implemented the 'domainSuspend' callback in libvirt for my hypervisor (see test.c or qemu_internal.c for reference) When using the Red Hat Virtual Manager (after connecting to my hypervisor), clicking on a domain row, then clicking the 'open' button at the botton right of the window, I get a new window where I can click the 'Pause' button for instance. When I do this, the 'domainSuspend' callback is entered twice as shown in my debug code below. Why is this happening? Is it a bug? So somewhere in the RHVM python code, this call is getting activated twice.
