[Xen-devel] Unresolved - qemu-dm crash under high dom0 disk load
This is regarding a long unresolved issue with HVM qemu-dm crashing under heavy Dom0 IO load. I decided to make a new thread on this seeing that I found many old ones scattered about with no resolution: Here are old threads regarding the same/similar issue http://lists.xensource.com/archives/html/xen-users/2007-08/msg00135.html http://lists.xensource.com/archives/html/xen-users/2007-07/msg00624.html Old bug reports of the issue: http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=542 http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1038 In 1038, spam@abma.de _incorrectly_ reports it is fixed in 3.1.1 -- Not only can I find any evidence of this, I can EASILY reproduce the crash over and over with 3.1.3-rc2. I have a dev. Xen box available for anyone who wants access for stack traces, ect. Unfortunately I myself do not have enough knowledge to find the problem myself, however I am available to instruct on how to produce the bug, run stack traces, help organize this effort, and provide unrestricted access to this dev machine if needed. -- Randy McAnally Fast Serv Networks, LLC 619-819-8252 x201 619-819-9443 fax _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

If this solves the problem, it would be nice to slide it into 3.1.3 final.> -----Original Message----- > From: xen-devel-bounces@lists.xensource.com > [mailto:xen-devel-bounces@lists.xensource.com]On Behalf Of Keir Fraser > Sent: Wednesday, January 30, 2008 9:33 AM > To: Randy McAnally; xen-devel@lists.xensource.com > Subject: Re: [Xen-devel] Unresolved - qemu-dm crash under > high dom0 disk > load > > > Please try the attached patch. > > -- Keir > > On 30/1/08 16:09, "Randy McAnally" <rsm@fast-serv.com> wrote: > > > This is regarding a long unresolved issue with HVM qemu-dm > crashing under > > heavy Dom0 IO load. > > > > I decided to make a new thread on this seeing that I found > many old ones > > scattered about with no resolution: > > > > Here are old threads regarding the same/similar issue > > > > > http://lists.xensource.com/archives/html/xen-users/2007-08/msg00135.html> http://lists.xensource.com/archives/html/xen-users/2007-07/msg00624.html > > Old bug reports of the issue: > > http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=542 > http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1038 > > In 1038, spam@abma.de _incorrectly_ reports it is fixed in 3.1.1 -- Not only > can I find any evidence of this, I can EASILY reproduce the crash over and > over with 3.1.3-rc2. > > I have a dev.

Sure. I''m confident to slip this one in without doing another rc. -- Keir On 30/1/08 17:37, "Dan Magenheimer" <dan.magenheimer@oracle.com> wrote:> If this solves the problem, it would be nice to slide it into 3.1.3 final. > >> -----Original Message----- >> From: xen-devel-bounces@lists.xensource.com >> [mailto:xen-devel-bounces@lists.xensource.com]On Behalf Of Keir Fraser >> Sent: Wednesday, January 30, 2008 9:33 AM >> To: Randy McAnally; xen-devel@lists.xensource.com >> Subject: Re: [Xen-devel] Unresolved - qemu-dm crash under >> high dom0 disk >> load >> >> >> Please try the attached patch. >> >> -- Keir >> >> On 30/1/08 16:09, "Randy McAnally" <rsm@fast-serv.com> wrote: >> >>> This is regarding a long unresolved issue with HVM qemu-dm >> crashing under >>> heavy Dom0 IO load. >>> >>> I decided to make a new thread on this seeing that I found >> many old ones >>> scattered about with no resolution: >>> >>> Here are old threads regarding the same/similar issue >>> >>> >> http://lists.xensource.com/archives/html/xen-users/2007-08/msg > 00135.html >> http://lists.xensource.com/archives/html/xen-users/2007-07/msg00624.html >> >> Old bug reports of the issue: >> >> http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=542 >> http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1038 >> >> In 1038, spam@abma.de _incorrectly_ reports it is fixed in 3.1.1 -- Not only >> can I find any evidence of this, I can EASILY reproduce the crash over and >> over with 3.1.3-rc2. >> >> I have a dev.
