Steps:
1. check whether the link library changed
# ldd /usr/lib64/libvirt/lock-driver/sanlock.so
For libvirt-0.9.4-17
# ldd /usr/lib64/libvirt/lock-driver/sanlock.so
linux-vdso.so.1 => (0x00007fff86f4a000)
libsanlock.so.1 => /usr/lib64/libsanlock.so.1 (0x00007fce69d2b000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007fce69b0f000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007fce6990a000)
libc.so.6 => /lib64/libc.so.6 (0x00007fce69569000)
librt.so.1 => /lib64/librt.so.1 (0x00007fce69361000)
libaio.so.1 => /lib64/libaio.so.1 (0x00007fce6915f000)
libblkid.so.1 => /lib64/libblkid.so.1 (0x00007fce68f3e000)
libwdmd.so.1 => /usr/lib64/libwdmd.so.1 (0x00007fce68d3b000)
/lib64/ld-linux-x86-64.so.2 (0x000000306cc00000)
libuuid.so.1 => /lib64/libuuid.so.1 (0x00007fce68b36000)
For libvirt-0.9.4-18
# ldd /usr/lib64/libvirt/lock-driver/sanlock.so
linux-vdso.so.1 => (0x00007fff4337b000)
libsanlock_client.so.1 => /usr/lib64/libsanlock_client.so.1 (0x00007f6120ad5000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f61208b9000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007f61206b4000)
libc.so.6 => /lib64/libc.so.6 (0x00007f6120313000)
/lib64/ld-linux-x86-64.so.2 (0x0000003b73400000)
As desired, changed:
From
libsanlock.so.1 => /usr/lib64/libsanlock.so.1 (0x00007fce69d2b000)
To
libsanlock_client.so.1 => /usr/lib64/libsanlock_client.so.1 (0x00007f6120ad5000)
Also follow the steps in:
https://bugzilla.redhat.com/show_bug.cgi?id=578121#c13
# rpm -q libvirt qemu-kvm kernel
libvirt-0.9.4-19.el6.x86_64
qemu-kvm-0.12.1.2-2.197.el6.x86_64
kernel-2.6.32-210.el6.x86_64
Result:
1. start two guest using one exact disk:
# virsh create demo1.xml
Domain demo1 created from demo1.xml
[root@intel-i7-12-4 ~]# virsh create demo2.xml
error: Failed to create domain from demo2.xml
error: Failed to acquire lock: File exists
2. start two guests on two hosts with same img file on same nfs mount dir
On host 1:
# virsh create demo1.xml
Domain demo1 created from demo1.xml
# ll -aZ /var/lib/libvirt/sanlock/
-rw-------. root root system_u:object_r:nfs_t:s0 5a2fc591bd45bf258255dc0055a7c5e6
-rw-r--r--. root root system_u:object_r:nfs_t:s0 disk.img
-rw-------. root root system_u:object_r:nfs_t:s0 __LIBVIRT__DISKS__
On host 2:
# virsh create demo2.xml
error: Failed to create domain from demo2.xml
error: internal error Failed to acquire lock: error -243
Basic operations work fine for libvirt, so this is fixed.
