Public bug reported:
[Impact]
* vhost-user falls back to virtio-net which causes performance lose
without specifying the vhostforce option. But it should be the default
behavior for vhost-user, since guests using PMD doesn't support msi-x.
[Test Case]
create a vhost-user virtio backend without specifying the vhostforce option, i.e. -netdev type=vhost-user,id=mynet1,chardev=<char_dev_for_the_controll_channel>
start the VM
vhost-user is not enabled
[Regression Potential]
* none
vhost user nic doesn't support non msi guests(like pxe stage) by default.
Vhost user nic can't fall back to qemu like normal vhost net nic does. So we should
enable it for non msi guests.
The problem has been fix in qemu upstream -
http://git.qemu.org/?p=qemu.git;a=commitdiff;h=24f938a682d934b133863eb421aac33592f7a09e.
And the patch needs to be backported to 1:2.2+dfsg-5expubuntu9.8 .

* vhost-user falls back to virtio-net which causes performance lose
without specifying the vhostforce option. But it should be the default
behavior for vhost-user, since guests using PMD doesn't support msi-x.
[Test Case]
create a vhost-user virtio backend without specifying the vhostforce option, i.e. -netdev type=vhost-user,id=mynet1,chardev=<char_dev_for_the_controll_channel>
start the VM
vhost-user is not enabled
[Regression Potential]
* none
vhost user nic doesn't support non msi guests(like pxe stage) by default.
Vhost user nic can't fall back to qemu like normal vhost net nic does. So we should
enable it for non msi guests.
The problem has been fix in qemu upstream -
http://git.qemu.org/?p=qemu.git;a=commitdiff;h=24f938a682d934b133863eb421aac33592f7a09e.
And the patch needs to be backported to 1:2.2+dfsg-5expubuntu9.8 .

Hello Liang, or anyone else affected,
Accepted qemu into kilo-proposed. The package will build now and be
available in the Ubuntu Cloud Archive in a few hours, and then in the
-proposed repository.
Please help us by testing this new package. To enable the -proposed
repository:
sudo add-apt-repository cloud-archive:kilo-proposed
sudo apt-get update
Your feedback will aid us getting this update out to other Ubuntu users.
If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-kilo-needed to verification-kilo-done. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-kilo-failed. In either case, details of your testing
will help us make a better decision.
Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in
advance!

Status in qemu source package in Wily:
Fix Released
Bug description:
[Impact]
* vhost-user falls back to virtio-net which causes performance lose
without specifying the vhostforce option. But it should be the default
behavior for vhost-user, since guests using PMD doesn't support msi-x.
[Test Case]
create a vhost-user virtio backend without specifying the vhostforce option, i.e. -netdev type=vhost-user,id=mynet1,chardev=<char_dev_for_the_controll_channel>
start the VM
vhost-user is not enabled
[Regression Potential]
* none
vhost user nic doesn't support non msi guests(like pxe stage) by default.
Vhost user nic can't fall back to qemu like normal vhost net nic does. So we should
enable it for non msi guests.
The problem has been fix in qemu upstream -
http://git.qemu.org/?p=qemu.git;a=commitdiff;h=24f938a682d934b133863eb421aac33592f7a09e.
And the patch needs to be backported to 1:2.2+dfsg-5expubuntu9.8 .
