I edited the line as "kernel /xen-3.0.gz hvm_debug=1" I did not *see* any HVM_DBG_LOG messages .I was of course looking for the ones in "vmx_do_msr_read" function in vmx.c I issued "dmesg" and "xm dmesg" in both guest and host OS. Any ideas why this is not working? Regards Shobha Ranganathan "The significant challenges we face cannot be resolved at the same level of thinking we were at when we created them."

Any ideas why this is not working? Setting hvm_debug=2 may work better, as the value 1 will only print debug messages at DBG_LEVEL_0 (1 << 0). Or you could set it to 3, to get both the level 0 and level 1 debug output. Or set it to "15" to get "all numbered levels". xm dmesg should show these prints, but of course, it DOES assume that you set the right bit in the level.

Thanks for your response I built xen with Make world XEN_TARGET_X86_PAE=y debug =y (do I have this correct ??) Make install Depmod Mkinitrd..... I also edited the grub line as "kernel /xen-3.0.gz hvm_debug=15" (I changed this after your email) No I do not see any messages.... ________________________________ From: xen-users-bounces@lists.xensource.com [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of Ranganathan, Shobha Sent: 31 October 2006 17:45 To: xen-users@lists.xensource.com Subject: [Xen-users] hvm_debug option in Xen works ?
