If we only config debug option for output values, we got:
604+0000: 12010: debug : lxcContainerWaitForContinue:392 : Wait continue
on
fd 21
If we config filter option as "1:+lxc", we got:
2013-10-22 02:24:30.365+0000: 13579: debug :
lxcContainerWaitForContinue:392
: Wait continue on fd 12
/usr/libexec/libvirt_lxc(virLogMessage+0x97)[0x7f2e1bdfa387]
/usr/libexec/libvirt_lxc(lxcContainerWaitForContinue+0x4b)[0x7f2e1bd7346b]
/usr/libexec/libvirt_lxc(+0x3197b)[0x7f2e1bd7b97b]
/usr/libexec/libvirt_lxc(main+0xcdf)[0x7f2e1bd70e4f]
/lib64/libc.so.6(__libc_start_main+0xf5)[0x7f2e19761b75]
/usr/libexec/libvirt_lxc(+0x27065)[0x7f2e1bd71065]
We still can't see who is the caller, and we got too many logs.
Additionally, filters with long name like ' lxcContainerWaitForContinue'
will not take effect.
With this patch, we got:
17931: debug : lxcContainerWaitForContinue:394 : virLXCControllerRun wait
continue on fd 12
I think we still need this patch.
Thanks!
