Hi, all,
This is KVM biweekly test result against kvm.git: 647e9ec3b543ea04d49a7323dfe0070682ed8465 and qemu-kvm.git: 7811d4e8ec057d25db68f900be1f09a142faca49.

In the last month, KVM testing was blocked by one qemu-img issue and two qemu build issues. Now the qemu build issue and qemu-img bug all get fixed.

One issue got fixed:
================================================
1. new Qemu-img can not create qcow image on read-only image

2. ltp diotest running time is 2.54 times than before

3. 32bits Rhel5/FC6 guest may fail to reboot after installation
https://sourceforge.net/tracker/?func=detail&atid=893831&aid=1991647&group_id=180599
4. perfctr wrmsr warning when booting 64bit RHEl5.3
https://sourceforge.net/tracker/?func=detail&aid=2721640&group_id=180599&atid=893831
5. [SR] qemu return form "migrate " command spend long time

Can you check the performance of this with cache=writeback?

The common on the report referring to cache=writethrough is incorrect (I 
think?)

Hi, Avi

I checked cache=writeback parameter, the diotest performance is much worse than "no this parameter"(about 20 times).

Followed qemu help, my command is "qemu-system-x86_64  -m 512 -smp 4  -net nic,macaddr=00:16:3e:79:0c:db,model=rtl8139 -net tap,script=/etc/kvm/qemu-ifup -hda /share/ltp_guest.img -drive cache=writeback", is it right?

When booting guest with cache=writeback, there are some hdb drive Error printed in guest, and guest booting very slow.


Thanks,
Xudong

You need to fold the -hda parameter into -driver, so the whole command 
line becomes

qemu-system-x86_64  -m 512 -smp 4  -net nic,macaddr=00:16:3e:79:0c:db,model=rtl8139 -net tap,script=/etc/kvm/qemu-ifup -drive file=/share/ltp_guest.img,cache=writeback


-hda is deprecated, it forces cache=writethrough.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

Okay, cache=writeback can improve 28% performance of diotest, it cost 135 seconds which cost 182 sconds with cache=writethrough.
But in the report of bug, there was 2.53 times downgrade performance than before, so maybe still need somewhere tuning.

Can you try creating the image with

   qemu-img create -f qcow2 -o cluster_size=4096 guest.img <size>

That reduces the cluster size to 4096, maybe that helps diotest.
