Change in vdsm[master]: vm: per-attribute monitor response check
by fromani＠redhat.com 21 Apr '15

21 Apr '15

Francesco Romani has uploaded a new change for review. Change subject: vm: per-attribute monitor response check ...................................................................... vm: per-attribute monitor response check the responsiveness of the monitor is reported through a single instance variable, which is updated after each libvirt call. If one single call goes in timeout, while the others go well, due to interplay between timeouts and polling interval, it can happen that reported status bounces back and forth between 'Up' and 'Not Responding'. This patch address this behaviour by keeping track of the timeouts per-dom-attribute instead of per-dom, and reports the monitor as not respondig if, and until, at least one had a timeout in the last call.

Change in vdsm[master]: vm: make new timekeeping revertable
by fromani＠redhat.com 30 Mar '15

30 Mar '15

Francesco Romani has uploaded a new change for review. Change subject: vm: make new timekeeping revertable ...................................................................... vm: make new timekeeping revertable The commit Icb0752e54a4cb9ff609b8ddfaf5c8fe2ed5b9e72 implemented the new timekeeping options recommended by QEMU developers. In order to maximize the backward compatibility and to deal with possible regression with old guests, this patch makes the new timekeeping settings revertable by exposing a new configuration variable. The default is enabled because those settings, being recommended, are supposed to be safe.

Change in vdsm[master]: vdsm: Refactoring of retrieving device info from xml
by Vinzenz Feenstra 23 Oct '14

23 Oct '14

Vinzenz Feenstra has uploaded a new change for review. Change subject: vdsm: Refactoring of retrieving device info from xml ...................................................................... vdsm: Refactoring of retrieving device info from xml Reworked a bit the retrieval of device info from the libvirt domain xml. Now VDSM won't parse the code in lastXmlDesc every time and the retrieval of elements from the domain xml has been a bit abstracted. Additionally the retrieval of an alias has been moved into a separate function call to make the readability a bit better.
