[libvirt PATCH] api: disallow virDomainAgentSetResponseTimeout() on read-only connections

[libvirt PATCH] qemu: fix response timeout for agent guest-sync
by Jonathon Jongsma 23 Mar '20

23 Mar '20

The agent 'guest-sync' command historically had a 5s response timeout which was different from other agent commands, which waited forever. When we added the ability to customize the response timeout for guest agent commands, we intended to continue to use 5s for 'guest-sync' when the user specified a response timeout greater than 5s, and use the user-specified timeout if it was below 5s. Unfortunately, when attempting to determine whether the user-specified timeout was less than 5s, we were comparing against an enum value of VIR_DOMAIN_QEMU_AGENT_COMMAND_DEFAULT (which is -1) rather than against the actual time value that it represented (5). This change makes it so that 'guest-sync' now uses the user-specified tiemout if it is less than 5s.

[libvirt PATCH] qemu: ensure domain event thread is always stopped
by Daniel P. Berrangé 23 Mar '20

Berrangé <berrange(a)redhat.com> Date: Wed Feb 12 12:26:11 2020 +0000 qemu: start/stop an event loop thread for domains A bogus comment was added claiming we didn't need to shutdown the event thread in the qemuProcessStop method, because this would be done in the monitor EOF callback. This was wrong because the EOF callback only runs in the case of a QEMU crash or a guest initiated clean shutdown & poweroff. In the case where the libvirt admin calls virDomainDestroy, the EOF callback never fires because we have already unregistered the event callbacks. We must thus always attempt to stop the event thread in qemuProcessStop. Reported-by: Peter Krempa <pkrempa(a)redhat.com> Signed-off-by: Daniel P.

GSOC'20: Add support for Jailhouse hypervisor to libvirt.
by PRAKHAR BANSAL 21 Mar '20

21 Mar '20

Hello All, My name is Prakhar Bansal and I am a graduate student in Computer Engineering at Iowa State University, US. I have experience with Analysing Performance of Applications running inside multiple virtual machines hosted by the libvirt QEMU-KVM through virt-manager. I am interested in working on the project to develop a Libvirt driver for the Jailhouse hypervisor. I looked into the initial attempt on the Jailhouse driver which seems to be based on the Jailhouse command-line interface. I am currently looking into learning and understanding the kernel APIs for jailhouse hypervisor.
