[Xen-devel] Debugging hvmloader and vmxassist
Hi there, I have been trying unsuccessfully to boot FreeBSD on Xen 3.0.4-testing.>From reading the mailing list I understand the problem with emulatingbig real mode. I would like to debug hvmloader and vmxassist to see if I can fix the issue. There are lots of printf statements in hvmloader and vmxassist. I am wondering how I can redirect them to the qemu-dm.<pid>.log log file. Please let me know if anyone on the list has a suggestion. Thanks, Sanjee _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
I thought they were already redirected there or to the regular xend logs, but can''t check on this until I get back from vacation. Peace.

You may have more luck with the V2E tree: http://xenbits.xensource.com/ext/xen-unstable-hvm.hg There are lots of printf statements in hvmloader and> vmxassist.

you can use this patch to get the log in your qemu log file. -Xin ________________________________ From: Sanjeepan, Vivekananthan Sent: Thursday, January 04, 2007 2:27 AM To: xen-devel@lists.xensource.com Subject: Debugging hvmloader and vmxassist Hi there, I have been trying unsuccessfully to boot FreeBSD on Xen 3.0.4-testing.

Hi, I think it is impossible to send the print message of hvmloader to qemu directly. Becuase before qemu could work(such as show message in screen with its VGA driver), the VGA bios must be installed, but as wo konw, the installiation VAG bios is done by hvmloader.Until hvmloader and bios(including system bios, vga bios, etc) have done, then the qemu can work. Although we can not do this directly, you can store the message of hvmloader in a big buffer, when the qemu can work, then let qemu get buffer to its screen or logfile. -- View this message in context: http://xen.1045712.n5.nabble.com/Debugging-hvmloader-and-vmxassist-tp2499660p4412817.html Sent from the Xen - Dev mailing list archive at Nabble.com. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

The OP is using "nabble" which is a web archive with a posting
interface. The posting interface sends emails which end up on our
list.
Lars, can we block this somehow ? We do not want people using a web
form to email xen-devel.
Ian.
