List, That patch that is referenced in the bugzilla : ... after reverting bef0fd59 in qemu-kvm, this issue doesn't exist. ... That is the exact same patch I had problems with a few weeks ago in iSCSI. As it turned out, it was NOT that patch that was buggy, but it exposed bugs in the iscsi block driver that made all I/O sudddenly take 55ms when booting from the BIOS, thus making the boot process tkae forever, andd it looked hung with a black screen, doing one i/o at a time 55ms apart. See http://lists.nongnu.org/archive/html/qemu-devel/2012-05/msg02716.html Maybe the backend used here has the same bug that I had in block/iscsi.c which was basically failing to call 'qemu_notify_event()' properly. Would be a weird coincidence otherwise since the symptoms are so similar, and they were both triggered by that same patch. I would check how the events are set up in the backend used here and check if perhaps that backend has the same bug iscsi had. regards ronnie sahlberg On Thu, Jun 7, 2012 at 6:38 PM, Ren, Yongjie <yongjie.ren@xxxxxxxxx> wrote: >> -----Original Message----- >> From: kvm-owner@xxxxxxxxxxxxxxx [mailto:kvm-owner@xxxxxxxxxxxxxxx] >> On Behalf Of Avi Kivity >> Sent: Thursday, June 07, 2012 3:28 PM >> To: Michael Tokarev >> Cc: KVM list >> Subject: Re: 1.1 release? >> >> On 06/07/2012 10:19 AM, Michael Tokarev wrote: >> > On 07.06.2012 11:13, Avi Kivity wrote: >> >> On 06/07/2012 10:10 AM, Michael Tokarev wrote: >> >>> Are there any issues with 1.1 release of qemu-kvm? >> >  >> >> Yes, there is a regression with IDE PIO that can hang a guest on boot. >> > >> > Any pointers on this? >> >> See the thread started by Yongjie Ren. >> > This bug is here. > https://bugs.launchpad.net/qemu/+bug/1002121 > The latest new is: after reverting bef0fd59 in qemu-kvm.git, it can work fine. > For detailed info, please look at the thread with below subject. > "Biweekly KVM Test report, kernel 51bfd299... qemu a1fce560..." > >> > >> > I were testing 1.1-rc with various guests and it all works more or >> > less okay so far, but I didn't try pio mode. >> > >> >> The bios uses it. >> >> -- >> error compiling committee.c: too many arguments to function >> -- >> To unsubscribe from this list: send the line "unsubscribe kvm" in >> the body of a message to majordomo@xxxxxxxxxxxxxxx >> More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
