Re: [libvirt] [PATCH 1/2] Revert "libxl: send lifecycle event on suspend"

A libxl event with shutdown reason LIBXL_SHUTDOWN_REASON_SUSPEND is sent after a domain is successfully suspended, which could result from suspending the domain to file (virDomainSave), suspending it to socket (virDomainMigrate), or suspending it to memory (virDomainPMSuspendForDuration). Commit d00c77ae changed the event handler to always set domain state to VIR_DOMAIN_PMSUSPENDED when LIBXL_SHUTDOWN_REASON_SUSPEND is received. The causes a persistent domain to show state "pmsuspended" after a successful migrate or save operation. Revert the commit and ignore the suspend event as before. This reverts commit d00c77ae45c7d9fd90384f01cd8b04c54f501e96. Signed-off-by: Jim Fehlig <jfehlig(a)suse.com&gt; ---
