Biweekly KVM Test report, kernel 51138ead... qemu df85c051...
Hi All, This is KVM test result against kvm.git 51138ead07c549ee3dbc0d08dcf8e93487b85f83 based on kernel 2.6.39-rc2+, and qemu-kvm.git df85c051d780bca0ee2462cfeb8ef6d9552a19b0. We found no bug and no fix in our nightly test during the past two weeks. But we found a build error in kvm.git upstream. And Clemens gave a patch for this issue. “arch/x86/kvm/emulate.c:4095:25: error: macro wbinvd passed 1 arguments, but takes just 0”. The qemu [vt-d] bug 754591 we reported in our last test report is reproduced by Alex, and he is fixing it. New issue: Fixed issue: Old Issues: 1. ltp diotest running time is 2.54 times than before https://sourceforge.net/tracker/?func=detailaid=2723366group_id=180599atid=893831 2. perfctr wrmsr warning when booting 64bit RHEl5.3 https://sourceforge.net/tracker/?func=detailaid=2721640group_id=180599atid=893831 3.

Re: [PATCH V3 0/8] macvtap/vhost TX zero copy support
On Thu, 2011-04-21 at 10:29 -0400, Jon Mason wrote: Why are only these 3 drivers getting support? As far as I can tell, the only requirement is HIGHDMA. If this is the case, is there really a need for an additional flag to support this? If you can key off of HIGHDMA, all devices that support this would get the benefit. Agreed. So far, I have only verified these three 10Gb NICs we have in our lab. We can enable all devices which support HIGHDMA.

With this zerocopy patch, the issue becomes more severe, guest io_exits has tripled than before, so the performance is not good. Once the TX overrun problem has been addressed, I will retest the small message size performance.
