RE: Critical Xen bug on Debian Squeeze, suspecting package xen-hypervisor-4.0-amd64

Two cases: 1) HVM DomU's : xm create sends a command to qemu, the parameter '-vcpu_avail'. But on newer version of qemu, parameters had changed (it's only 'vcpu_avail'): so HVM domain cannot be started. Here is the error line : /usr/lib/xen/bin/qemu-dm: invalid option -- '-vcpu_avail' 2) Others DomU's (include pvops domains ! so not it's not the kernel): they freeze at startup, with cpu @ 100%. No specific logs, no errors reported, just only r status on xm list and no boot with cpu at max. Then, in my case, it's obvious these are regression on squeeze. Why ? Because on my 3 dom0's, only 2 of them are updated. And the old one works *perfectly*, both for HVM and Pvops DomU's. Dom0 are similar (same hardware, dell 2970 with opteron 2423 HE) On old working Dom0 : $ aptitude show xen-hypervisor-4.0-amd64 Version : 4.0.1-1 $ aptitude show qemu-system Paquet : qemu-system Version : 0.12.5+dfsg-2 - On updated Dom0's : $ aptitude show xen-hypervisor-4.0-amd64 Version : 4.0.1-2 $ aptitude show qemu-system Version : 0.12.5+dfsg-3 I know this report is general, so if you want further details, I'll be ready to do some tests today. Have you filed a bug over on the Debain BTS for what you believe to be a bug in the package xen-hypervisor-4.0-amd64? Can you test if this behaviour exist in the i386 package?

Sorry, I can't test for x86 only. And no, I didn't report the bug so far.. And about downgrade, it's not a solution for me : the kernel which made disappear the regression have a bug with kernel oops when I made vgchange for LVM (which is corrected in current version). :( Regards, Olivier.
