Fix built for 5.3 in $ brew latest-pkg dist-5E-qu-candidate xen Build Tag Built by ---------------------------------------- -------------------- ---------------- xen-3.0.3-65.el5 dist-5E-qu-candidate berrange * Thu May 8 2008 Daniel P. Berrange <berrange> - 3.0.3-65.el5 - Remove blktap sharing patch which prevents guests with large numbers of disks booting (rhbz #445476) Please clone this bug for 5.2.z Hi Berrange-san, We tested start domain with more than 4 disks applying blktap patch. The result is no problem. We think the patch is not concerning with your test result. We would like to check the race condition of other domain's disk and test again. Thank you. Fujitsu) Nishi The problem is a race condition that depends on many factors. On some machines > 3 disks causes a problem, on other machines it only impacts > 8 disks. When it hits the errors are clearly coming from the blktap sharing patch. The problem is that it is trying to read info about other disks out of xenstore, while XenD is still writing the entries into xenstore. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.
