We cannot startup IA32/IA32pae unmodified linux guest OS. Booting 32bit VMX domain will stop at printing "ACPI: Unable to locate RSDP". Booting 32pae VMX domain will get a kernel panic. No abnormal info found in serial output. It''s interesting that sometime we can boot Windows 2003. Booting Windows SP1/SP2 G...

I tried latest xen and linux-xen staging tree, but failed to run HVM domain on x86-64 environment. domU creation is OK. However the weird thing is not HVM domain itself. Instead system crashed on dom0 context. I saw once with some stack dump that xen''s page fault handler is executed on a dom0''s stack which then causes nested page fault due to unable to fetch vcpu pointer.

Save/restore is ok against staging tree''s changeset 15020: d2ef85c6bf84, but is NOT ok against changeset 15021: 00618037d37d (Update to qemu 0.90). I use IA32pae HV; both SMP Windows 2K3 and FC5 can''t be saved properly. After "xm save dom_id 1.save" returns, Qemu window disappears, but "xm vcpu-list" still shows the domain has not been killed. If I "xm dest" the dom manually by force, and run "xm restore 1.save...

...PAE SMP HVM domain may cause xen0 CRASH. It won''t happen every time, but if we run the cases for several times, HVM domain will make xen0 crash then. And we also met the issue in latest cs 11730. Old issues: 1. Win2k installation with ACPI enabled will give a blue screen. On all the IA32/IA32pae/IA32e HV, installation of Win2k with ACPI will be block with a blue screen, saying the Win2k BIOS is not compliant with ACPI specification. 2. 2. FC5 IA32 SMP HVM Guest crash when booting SMP Guest It will occur on both IA32p/IA32e host. Always make Guest crash. And we can boot up FC5 IA32 UP HVM...

We (Michael Fetterman, George Dunlap and I) have been working over the last while on a full replacement for Xen''s shadow pagetable support. This mail contains some design notes, below; a patch against xen-unstable, giving a snapshot of the current state of the new shadow code, is at http://www.cl.cam.ac.uk/~tjd21/shadow2.patch Comments on both are welcome, although the code is not

We saw these issues in recent ChangeSet: 1. Reboot fail in Guest OS: Reboot in guest will close current qemu windows but does not create a new qemu window to restart 32bit HV/xen0: 2. 4 LTP math cases(float_bessel, float_exp_log, float_power and float_trigo) sometime fail. (775) 3. Kernel build in VMX may meet kernel panic. It complains like: "<0> Kernel panic - not syncing:
