[Libvirt-cim] [PATCH] for cimtest

[Osier Yang]

Hi kaitlin. 

I tested on three machines.

===Machine A===
[root at dhcp-66-70-159 ~]# ls -laut /boot/ | grep vmlinuz
-rw-r--r--  1 root root 2045656 Jan 14 08:40 vmlinuz-2.6.18-183.el5xen
-rw-r--r--  1 root root     158 Jan 14 06:15 .vmlinuz-2.6.18-183.el5.hmac
-rw-r--r--  1 root root 1953468 Jan  8 14:28 vmlinuz-2.6.18-183.el5
-rw-r--r--  1 root root     161 Dec 21 18:51 .vmlinuz-2.6.18-183.el5xen.hmac

[root at dhcp-66-70-159 ~]# find /boot/ | grep vmlinuz | egrep -v 'xen' | 
tail -n1
/boot/.vmlinuz-2.6.18-183.el5.hmac

==Machine B====
[root at dhcp-66-70-128 tmp]# ls -laut /boot/ | grep vmlinuz
lrwxrwxrwx  1 root root      22 Jan 15 10:52 vmlinuz -> 
vmlinuz-2.6.18-160.el5
-rw-r--r--  1 root root 1931964 Dec 23 13:44 vmlinuz-2.6.18-160.el5
-rw-r--r--  1 root root 1931580 Aug  1 05:02 vmlinuz-2.6.18-158.el5
-rw-r--r--  1 root root 2029233 Aug  1 05:02 vmlinuz-2.6.18-158.el5xen
-rw-r--r--  1 root root     158 Jul 28 05:41 .vmlinuz-2.6.18-160.el5.hmac
-rw-r--r--  1 root root     161 Jul 14  2009 .vmlinuz-2.6.18-158.el5xen.hmac
-rw-r--r--  1 root root     158 Jul 14  2009 .vmlinuz-2.6.18-158.el5.hmac

[root at dhcp-66-70-128 tmp]# find /boot/ | grep vmlinuz | egrep -v 'xen' | 
tail -n1
/boot/.vmlinuz-2.6.18-160.el5.hmac

======Machine C===============
[root at amd-4450b-4-1 ~]# ls -laut /boot/ | grep vmlinuz
-rw-r--r--  1 root root 1953468 Jan 12 21:29 vmlinuz-2.6.18-183.el5
-rw-r--r--  1 root root 2045656 Jan 12 21:29 vmlinuz-2.6.18-183.el5xen
-rw-r--r--  1 root root     161 Dec 22 07:51 .vmlinuz-2.6.18-183.el5xen.hmac
-rw-r--r--  1 root root     158 Dec 22 07:43 .vmlinuz-2.6.18-183.el5.hmac

[root at amd-4450b-4-1 ~]# find /boot/ | grep vmlinuz | grep -v 'xen' | 
tail -n1
/boot/vmlinuz-2.6.18-183.el5

so,  the result depends on the access time of ".vmlinuz-*.hmac".

that means the patch is not useless.  :)

Thanks and Regards
