kubevirt: [flaky ci][ipv6 lane] command SyncVMI failed: LibvirtError qemu unexpectedly closed the monitor KVM: Cannot allocate memory

Is this a BUG REPORT or FEATURE REQUEST?:

What happened:

The error happened on this test, but seems to be unrelated to the test itself - Networking VirtualMachineInstance with masquerade binding mechanism [test_id:1780]should allow regular network connection without a specific port number
