The hvm domain which is being debugged sometimes crashes with the following message: (XEN) Failed vm entry (exit reason 0x80000021) caused by invalid guest state (0). (XEN) ************* VMCS Area ************** (XEN) *** Guest State *** (XEN) CR0: actual=0x000000008005003b, shadow=0x000000008005003b, gh_mask=ffffffffffffffff ...[snip]... (XEN) DebugCtl=0000000000000000

There is a race condition between XEN_DOMCTL_SHADOW_OP_ENABLE_LOGDIRTY and HVMOP_track_dirty_vram hypercall. Although HVMOP_track_dirty_vram is called many times from qemu-dm which is connected via VNC, XEN_DOMCTL_SHADOW_OP_ENABLE_LOGDIRTY is called only once from a migration process (e.g. xc_save, libxl-save-helper). So the race seldom happens, but the following cases are possible.

Hi, We found a bug that rombios cannot get the correct BDF during rom_scan. This patch fixes rombios to get the BDF for calling INIT function.

The value of ACPI PM-Timer may be broken on save unless the timer mode is delay_for_missed_ticks. With other timer modes, vcpu->arch.hvm_vcpu.guest_time is always zero and the adjustment from its value is wrong. This patch fixes the saved value of ACPI PM-Timer: - don''t adjust the PM-Timer if vcpu->arch.hvm_vcpu.guest_time is zero. - consolidate calculations of PM-Timer to one

Hello I am trying to boot/install VM on XenClient. I would like to learn the way to install VM. Please teach the example of the operation and config file. (Especially, configuration file of method of displaying screen.) thanks. ========================================= [My Executed History] (1) I made a config file for VM(Windows XP:below). (2) I executed the following commands. # xenvm

I have a CentOS 5.2 Xen host, running several guest domains. Each guest domain has a single interface assigned to it. I am using both the network-bridge and vif-bridge scripts. On my only windows guest, the tap interface connected to the bridge keeps getting disabled. If I check "brctl show" the tap0 interface is not present, and there will be several message log entries indicating

Hi, This set of patches remarkably accelerates IDE PIO on HVM/IA64. I got a throughput of 2.11MB/sec in disk read performance. Without it, it was only 64kB/sec. I posted the prototype once. http://lists.xensource.com/archives/html/xen-devel/2006-12/msg00077.html The basic idea is to add a buffering mechanism in a hypervisor. I know this approach is not sophisticated. But there is no other good

Dear All, I'm very new Gluster FS user.... ...and apologize for my very poor english! :-) I have installed Gluster FS v. 1.3.12 on 2 server with Debian 4.05, in AFR with client side replication, explained in this page: http://www.gluster.org/docs/index.php/Setting_up_AFR_on_two_servers_with_client_side_replication Tested to work! :-) Now, my idea: Use a Xen Hypervisor with image disk

Hi, for debugging purposes I would like to see the existing xenstore watches and the waiters for the watch. The problem is, we got a EEXIST from xenstored while trying to set a watch from our guest. Is there a possibility to see this on the running xenstored? Thanks. Dietmar. -- Company details: http://ts.fujitsu.com/imprint.html

This patch rewrites the rtc/timeoffset entry so the VM''s record can be retrieved with the Java xmlrpc library. If the entry is ''None'' it upsets the xmlrpc parser. This fixes it, though maybe there''s a better place in xend to place similar code. Signed-off-by: Stefan Berger <stefanb@us.ibm.com> _______________________________________________ Xen-devel

Two things: 1. I''m not convinced ''xm crash'' is needed - ''xm destroy'' will do this (and if you want a dump, do ''xm dump'' followed by ''xm destroy'') 2. I don''t see the point of the --noreboot option on ''xm dump'' -- I think this command should simply live-dump the specified domain - as

Hello, I''ve modified tools/xenstore/xenstore_client.c to include a new utility, xenstore-chmod. This utility permits developers and administrators to manually change the permissions on arbitrary locations in XenStore from the command line. This is often helpful if you''re trying to debug an application that relies on XenStore and is encountering difficulties with permissions.
