@Timur,
tl;dr: the machine running the tests is overloaded, please buy more RAM.
> Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.7.5-20151012_
The host powering the VMs got overloaded, and its kernel have been heavily swapping.
As a result the qemu process got blocked for a very long time. This looks like an Ethernet
card lockup from the point of the view of the guest kernel.
Possible solutions:
1) Add more RAM to the host,
2) Use SSD for the host OS and swap partition (logical volume),
3) Use a different hard drive to store VMs images, so intensive guests IO does not interfere with host IO (in particular paging/swapping),
4) Restrict the load on the host
