I''m not seeing the problem that Fan Zhao is reporting, instead I get this one. Not sure if ti''s the same one or a different problem... This happens with my simple-guest [i.e. not using hvmloader, as I described before]. This worked fine yesterday.

When running test 5 in Memtest86+ v1.65, I got a "this opcode is not supported", so I decided to add it. It''s a compare operation, and it''s just the opposite of the already supported one (opcode 0x39), so it''s nothing spectacular. Why there''s a page-fault when this instruction gets executed, I haven''t got a clue, but I have a feeling that

I got latest (13601) yesterday evening. This doesn''t seem to work to do Restore (at least of the Windows test-image that I''ve been using for testing previously). The VM restores reasonably OK, but it jumps to an invalid address shortly after restoring, giving a D1 blue-screen error (DRIVER_IRQL_LESS_OR_EQUAL), which turns out to be "page-fault in driver" after I

attached is the vmx domain save/restore patch. works well for different guest/host combination W/O breaking domu save/restore according to my test. pls. first apply xiaowei''s qemu dm fix. ===know issue=== * shpage pfn * HV look for shpage pfn in an e820 entry when init. but some guest(win/em64t linux) will reuse this e820 ram, which cause losing shpage pfn when restore. so this

What are the settings that I must specify to have DomU be saved and then automatically started on reboot of the physical server? In my /etc/sysconfi/xendomains it points to a save folder (which does not exist) My configuration files are located at /vm/cfg/vm-xxxx/vm-xxxx.xen   In my config file I have: on_poweroff = ''destroy'' on_reboot = ''restart'' on_crash =

Hello, I''m trying to port one of our existing appliances (running on 64-bit Red Hat Enterprise Linux 6.4) to a Xen HVM guest . We''re seeing some very odd behaviour that doesn''t manifest on other platforms. The guest experiences intermittent lockups of a few seconds- shell sessions become unresponsive, and various software healthchecking in our application triggers,

Hi, When using lapic as timer source the hypervisor delivers timer interrupts late. In the source xen/arch/x86/hvm/vpt.c function create_periodic_time creates a timer element with a "bonus" of 50% of the desired time until the interrupt: pt->scheduled = NOW() + period; /* * Offset LAPIC ticks from other timer ticks. Otherwise guests which use * LAPIC ticks for

Hi, After c/s 18694 changed vHPET to vpt, for single HVM RHEL 5u1 guest idle case, our box will consume ~0.8W more power than before. The reason is two periodical vpts'' expires are hard to be aligned in the 50us soft timer SLOP. So we are considering a vpt specific enhancement which could try to just align periodical timers within vpt. A generic enhancement is to add a new interface

Not yet, but I don''t see any reason for it to work any differently. I simply used vmware because it was convenient. -Adam | -----Original Message----- | From: Simon Gao [mailto:gao@schrodinger.com] | Sent: Thursday, October 05, 2006 11:22 AM | To: Adam Crews -X (acrews - Xerox at Cisco) | Cc: xen-users@lists.xensource.com; Mike Freemon | Subject: Re: [Xen-users]

As you know, HVM save/restore broke recently because restored config miss guest memsize that used by xc_hvm_restore to locate some pfn. After discussion, we decided to remove the pfn deduction logic from restore side by adding a general memory layout. I have a patch for it. But then qemu broke, because it also require the memsize to locate the share page. We can''t use the previous

For an SMP Linux HVM guest with PV drivers inserted, when we do save/restore (or LiveMigration) for the guest, it might panic after it''s restored. The panic point is inside ap_suspend(): .... while (info->do_spin) { cpu_relax(); read_lock(&suspend_lock); HYPERVISOR_yield(); ----> guest might panic on the invocation of this function.

Hi koonz I noticed that you are using the cdrom parameter in the config file I believe that''s no longer used in recent versions of Xen. I am running debian etch here atm and am trying to virtualize windows guests aswell I am able to boot up windows with the following configs although they do tend to hang at some point during the installation. ----- Config windows xp ----- import os,

If anyone is still interested in this old thread, I have a rh7.3 image running under hvm. It''s a hack, but here''s what I did: Install rh7.3 in a vmware machine with vmware server.

Is there a way to get Windows to do an orderly shutdown (eg simulate a power button press) using the ''xm shutdown'' command? Thanks James _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi I''ve been running xen with linux guests for a while now and thought I''d try windows as I have a new server. All seemed to go fine except performance is *horrible* - I''m currently installing Win2003 SP2 and it''s been running over 12 hours (thank god for vnc) - each individual file is taking between 3 and 4 seconds each. Server is an intel E6600 with
