Hello!
I think I found another bug.
It started when I added new Linux VM with the following command:
/usr/local/bin/qemu-system-x86_64 -smp 4 -hda /mnt/epic.img -m 1024
-boot c -vnc :13 -runas kvm -daemonize -localtime -k en-us -net
nic,vlan=3,model=rtl8139,macaddr=00:0F:BB:BB:EC:AA -net
tap,vlan=3,script=/tmp/if-up3 -net
nic,vlan=0,model=rtl8139,macaddr=00:0F:BB:BB:EC:AB -net
tap,vlan=0,script=/tmp/if-up
Here is the log:
