KVM and virtual Mikrotik problem

RouterOS Virtualization
1

Hello,

Im running QEMU PC emulator version 0.9.1 (kvm-84) on my host i found a strange problem with running Mikrotik as virtual machine (v3.24) on my virtual MT i have two interfaces running for testing there are bridged everything is running fine (on low traffic under 1-2mbps) but problem occures when i try to switch network traffic (over 60mbps) to it network interface just hangs i found that resolution to this problem is to connect to the MT by the vnc (console) and simple disable/enable hanged interface. Does anybody have idea what can be the problem ?.

Linux interfaces:
br0 : eth1 vr1
br1 : eth2 vr2

MT interfaces:
bridge1: ether1(vr1) ether2(vr2)

ps. sure i know that i can bridge eth1 and eth2 interfaces together but thats not an idea (bridge in MT is only for testing)

did you try 3.27?..

p.s. always use the lates version for testing - nobody will fix old versions

yes i tried but when i bught license for MT version was 3.23 and now when i try to update to 3.27 or any other MT hangs at i can update to 3.24 only (dunno why)

I also got it working by only setting the -cpu switch set to anything except qemu64. It looks like qemu64 is the default. BTW, that’s a capital -M. Lowercase -m sets the memory allocation.
