Hi everyone, as what I''ve learned form this link<http://wiki.xensource.com/xenwiki/blktap>, i know that when i specify tap:aio I’m actually using the blktap driver and finally using "tapdisk" to wirite to raw image file. but the truth is even when i delete /usr/sbin/tapdisk the domU can still boot on my machine with tap:aio protocol after a deeper look into the scene,

Hello all, I''m using Red Hat Enterprise Linux 5 (with RH Virtualization) and a Dell Poweredge 2950 with 10 NICs. My virtual operating systems are all RHEL4, and I''ve installed 4 instances. I''m trying to set up the virtual operating systems so that the physical NICs are allocated to certain operating systems. Using the following tutorial:

NOTE: An applicable subset of this patch was also submitted to upstream qemu. SUMMARY: This patch fixes several bugs in serial.c (1) A typo in serial_save() where qemu_get_8s is called (should be qemu_put_8s) (2) No support provided in serial_load() for version_id == 1 (should unmarshal a 1 byte s->divider and should provide a default value for s->fcr (3) Call serial_ioport_write() to

Hello all, I have a PowerEdge 2950 that I am using to host Windows XP VM's under CentOS. I am experiencing poor performance in the Xen VM's. Any time I try to do something, the CPU usage (as reported by the Windows task manager) hits 100% for a few and then drops back down. This is causing the VM's to run sluggish and be quite annoying to use. Example.. I click IE.. cpu hits

There seems to be an outdated page to use PV drivers here: http://wiki.xensource.com/xenwiki/XenWindowsGplPv I''d be great if that could be updated. After installing the PV drivers in windows I didn''t notice any difference in performance at all. Windows says the drivers are working. Some more searching and reading and it appears that I do actually need to make some changes to

hi, I am using xen-unstable version and I can use the serial port to debug DomU openSuSE Linux with kgdb very well. But it doesn''t work when I am trying to debug DomU WinXP with windbg. I happened to find this link http://www.evilbitz.com/2006/12/13/howto-debugging-a-remote-windows-hvm-under-xen-using-windbg/, but it still doesn''t work for me. Any suggestions about this?

I hope this is not to far off topic. I have a Windows 2003 guest on a CentOS 5.5 KVM host. I need to use the serial port on the win2003 guest for the application it is serving. I have no idea what needs to be done but it looks like the linux host is trying to use the serial port as the priamary console but I don't really understand what that is or where it is configured. What I need is for

Okay, I've updated virtio serial drivers to latest ones. This did not help. Afterwards I've enabled "Show hidden devices" in Device manager of a guest os.In the "Other devices" section I can see two virtio serial ports with question marks (i did configure guest with 2 virtio channels). Is this a normal behaviour? Screenshot:

Hello, While testing Fedora 16 Xen PVHVM guests I noticed the following problem: When starting F16 PVHVM guest I can see the vifX.0 and tapX.0 interfaces appear on dom0, but after the guest kernel (Linux 3.1.0) starts and loads PVHVM drivers the vif/tap interfaces disappear from dom0.. so the bridge in dom0 doesn''t have any vifs/taps connected to it anymore. Has anyone seen that

Hi all, I''m having some problem migrating a simple domU between two hosts. Short question: xm migrate (live or not) fails even though either host is capable of running the VM.
