[Qemu-devel] [Bug 1556306] Re: vhost-user: qemu stops processing packets under high load of traffic
you can also add the project 'qemu-kvm' on the bug in order to get it into the ubuntu qemu-kvm bug list. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1556306 Title: vhost-user: qemu stops processing packets under high load of traffic Status in QEMU: New Bug description: Description of problem: - qemu socket becomes full, causing qemu to send incomplete SET_VRING_CALL messages to vhost-user backend (without proper fd set in ancillary data). - after some time, some interrupts are lost, causing the VM to stop transmitting packets.

apologize but I was corrected that for qemu issues. The bug should be in the following: Distribution: ubuntu package: qemu <--instead of project.

Correct, it is fixed in Qemu upstream.
