The original report was that 'Reset' does not work from GUI, like virt-manager or virsh. I think the expected outcome is like pushing the reset button on a physical board. Xen doesnt do it that way, no idea about others.
Sounds like you want libxl_domain_reboot then, perhaps with a fallback on ERROR_NOPARAVIRT for an HVM guest to sending a trigger.
Hrm, I don't think that's right . It should be a hard reset
http://libvirt.org/html/libvirt-libvirt.html#virDomainReset
destroy/start seems the correct way to implement this.
Yes, given that requirement it is. Sorry for the noise.
Would some sort of hard reset API be useful in libxl?
Sure. I think having an API that emulates a power reset button would be a nice addition to libxl's domain operations. The destroy/start approach incurs a small bit of overhead, which would be avoided with such an API. Clients (perhaps incorrectly) implementing their own notion of reset would also be avoided.
I think this ought to become pretty easy once Wei's patches to record the guest cfg in libxl are completed. Wei -- what do you think?
I don't think this "reset" API will need to record any state, i.e. this feature looks unrelated to my work. What do I miss? Wei.
