hi,all
I want to modify the xen source code and test something,
but where can I print the debug info?
I found and try this :
#define HVM_DBG_LOG(level, _f, _a...)
\
do {
\
if ( unlikely((level) & opt_hvm_debug_level) )
\
printk("[HVM:%d.%d] <%s> " _f "\n",
\
current->domain->domain_id, current->vcpu_id,
__func__,
\
## _a);
\
} while (0)
but I use dmesg and cat /var/log/xen/* , find nothing

regards,
yandong

thank you, by the way, except printk, are there any other methods I can use to debug? 2013/5/7 Shakeel Butt <shakeel.butt@gmail.com>> > but I use dmesg and cat /var/log/xen/* , find nothing > > > Since you are using printk in the hypervisor you should do "xl dmesg" > (or "xm dmesg") to get the messages. > > Shakeel >-- ---------------------------------------------------------- regards, yandong _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
