[Qemu-discuss] Colo perfmance

2017-02-27 Thread wangguang
Hi
I am testing QEMU COLO feature described here [QEMU
Wiki](http://wiki.qemu-project.org/Features/COLO).
I am testing io performance with iozone in  Primary VM.
And the io performance wth colo is mucher lower than which without colo when
writing a file in Primary VM.

Iozone –r 512k –i 0 –i 1 –s 2g –f /home/file_2G
not colo:
Write: 1544523
Rewrite:   1433098
Read: 696418
Reread:   721802

Colo:
Write: 138186
Rewrite:   138286
Read: 1754523
Reread:   1892802


Does anyon have plan to optimize the performance of colo? 
Any help is appreciated!

[Qemu-discuss] COLO test problem

2017-02-21 Thread wangguang
Hi,
I am testing QEMU COLO feature described here [QEMU
Wiki](http://wiki.qemu-project.org/Features/COLO) but I can't login vm in
VNC.VNC display "Guest has not initialized the display (yet)."
 I am using colo-v5.1-developing-COLO-frame-v21-with-shared-disk for
test,and VNC can login witout  "driver=quorum".
Has anyone ever run it successfully? Any help is appreciated!
