hvm_debug option in Xen works ?
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?

changing "hvm_debug" at runtime
Is it possible to change a xen parameter at runtime?
For some of the parameters it would make no sense to do so, but for
some, like "hvm_debug", it would be really useful.
Thanks
James

4.3.0-3 fresh build - hvmloader Triple fault on VCPU0
...1 xen packages from the Debian archive, things work fine.
However, when we compile the xen=4.3.0-3 source package ourselves, we run into an issue launching an HVM. As soon as the HVM bios is loaded, VCPU0 gets a triple fault and the HVM is destroyed (this is with "loglvl=all guest_loglvl=all hvm_debug=3" boot options).
