[ovirt-devel] OVIRT-3.5-TEST-DAY-3: replace XML-rpc with JSON-rpc

Hi everyone of this test day I played with the new JSON-rpc transport, which is enabled by default. I set up from scratch two hypervisors running on RHEL 6.5, while Engine was running on F19. I created everything from scratch and tested all the flows I known good enough, including less-then-common stuff. The list includes creating storage domains, VMs, hotplug/unplug disks, snapshots, migration, hibernation and dehibernation. On top of that, I prepared an environment to run more tests, that included create 200 VMs, started/stopped 100 of them to test. I kept an eye on the logs other than Engine. Everything I tried went OK, and logs look good to me. I run in a few hiccups, which I mention for the sake of completeness: - VDSM refused to start or run VMs initially: libvirt config included relics from past environment on the same box, not JSON-rpc fault. Fixed with new config and (later) a reboot. - Trying recovery, Engine took longer than expected to sync up with VDSM. I have not hard data and feeling is not enough to file a BZ, so I didn't. - Still trying recovery, one and just one time Engine had stale data from VDSM (reported two VMs as present which actually aren't). Not sure it was related to JSON-rpc, can't reproduce, so not filed a BZ. Since I need to continue profiling anyway (better late than never I guess), I include a couple of test to see if JSON-rpc makes any difference to JSON-rpc. Results will be posted on devel(a)ovirt.org and/or on the oVirt wiki. -- Francesco Romani RedHat Engineering Virtualization R & D Phone: 8261328 IRC: fromani
