hi, It looks that Xen currently only support ISA serial port, which is onboard. Is there any plan to support the PCI serial port? Thanks, Neo -- I would remember that if researchers were not ambitious probably today we haven''t the technology we are using! _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

hi, I just tried the tip of the xen-unstable branch. It looks that the Xen supports 64bit BARs now?

I think we need this feature at least for debugging purpose, right? Or, do we already have this feature?

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?

Hi, everyone, I installed the Xen3.1.0 based on Fedora8 and enter the Dom0 successfully. The kernel of dom0 is linux-2.6.18-xen0. But the Xorg could not start in the Dom0. When I use the "startx" command to start the X server, the error information is following: ......... (==) Using config file: "etc/X11/xorg.conf" (II) Module already built-in (II) Module already built-in

Hello Everyone, We have noticed that one of our servers xen Dom0 is restarting idiopathically. Atleast, we are not able to analyze the cause. I have checked the logs but couldn''t find anything relating to it. Are there any tools such as kdump (which doesn''t seem to work on xenified kernels) for catching the kernel crash snapshot. Regards, Sree Harsha Totakura Member, Open

I asked this a few weeks ago but didn''t get a response, so at the risk of being a nag, I''ll abbreviate and restate. I know there are other Xen specific debuggers, but I want to know if there''s any reason why SGI''s kdb, http://oss.sgi.com/projects/kdb, should not be included in a dom0 pv-ops kernel? While the patches apply cleanly and build, the result is that

Hi All, I am trying to attach floppy virtual image to Windows domU. Either it is not attaching or domU is not showing floppy drive? domU config: 1. disk = [ ''file:/root/xenwin.img,hda,w'', ''file:/opt/Windows-Xp.iso,hdc:cdrom,r'', ''file:/root/win-boot.img,fd:floppy,r'' ] boot = "cda" In above format the window domU is booting but

Hi, Is there any tool out there that can help me analyze a coredump? Thanks, David. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Box with fresh RELENG_7 panic under heavy network load (more than 50k connections). This panics seems to be senfile(2) related, because when sendfile disabled in nginx, I can't reproduce the problem.

Hello, There it is, all my computers on FreeBSD 9.1-RELEASE had panic. I can just say there is a problem in the 9.1-RELEASE because I had no panic before. What afraid me is that my production server also panic'ed a few days ago, fortunately it does not appears so often. This is a panic that happened on my desktop computer, with a graphic card. The crash usually appears when X starts. GNU

Hello, Since FreeBSD 9.1 I have strange problems with the distribution. Some servers are rebooting without any kernel panic, instanly. First i thought it's a problem with my KVM system, but one of my FreeBSD under a Dell R210 have the same problem. The servers concerned are now: - Monitoring server - LDAP test server - Some other servers, randomly (not in production). First i thought it's

I'm running 9.2-RC4 on a handful of desktop and server machines (both i386 and amd64). I have seen three panics (all vm_page_unwire) on one of those systems only (amd64 server) during the past week. The first two panics were triggered when shutting down the ntpd daemon (a recent development snapshot version of ntpd: 4.2.7p387). Exiting a later release (p388) has not triggered the panic.

9.2 PRERELEASE (today) / amd64 Hello, I'm seeing a panic while trying to build a poudriere repository. As far I can see it always happens when gam_server is started (ie xfce is running) and under disk load (poudriere bulk build) : (That is something new, the box was pretty stable) the complete crash dump (core.0.txt) is here: http://user.lamaiziere.net/patrick/panic_gam_server.txt Fatal

Fix the polling section of the hvc driver to use the global "last_hvc" variable, rather than the ttys.

Hi, all, The attached patches try to improve the current FLR logic. The idea is: removing the FLR logic from hypervisor and adding the improved logic in Control Panel. The current FLR logic in hypervisor has some issues: 1) Dstate transition is not guaranteed to properly clear the device state; 2) the current code for PCIe FLR is actually buggy: PCI_EXP_DEVSTA_TRPND doesn''t mean the
