If "what you are trying to achieve" is to run a multi-threaded application on multiple independent physical machines, then the the most famous answer ~20 years ago was "mosix". Feel free to spend some time playing with it. When I tried it, it did work as advertised, but as was quickly understood by many that were fascinated by it when first announced (at least, when the linux version was first announced), it's almost always the worst solution in terms of performance. It's still being developed, probably getting better over the years, but you are much better off splitting your work to multiple processes that are explicitly managed on separate machines. One way to do that, for your specific case, is what Tony suggested - split your network address range between the machines and let each scan a chunk of the range.

That in turn causes a timeout and fails the transaction.

Per your decision on what default route you want to have, adjust Engine or/and investigate how that route exists on the host. One option that this may have happened is if you used DHCP on the vm_traffic network and git the route through it.

[ovirt-users] Cannot import VM. Invalid time zone for given OS type. Attribute: vm.vmStatic
Need some magic here ... - 2 hosts CentOS 7.5.1804 with all the patch available, in the cluster - hosted engine from rpm ovirt-engine-appliance-4.2-20181113.1.el7.noarch with all the patch as well (manager Version 4.2.7.5-1.el7) 1) I re-install the hosts and the hosted engine from scratch 2) I imported the ISO, export and DATA domain from the SAN 3) I went to the DATA domain in the VM Import tab where I saw all the VMs 4) I imported the VM one after one BUT One of the VM (Windows 10 x64) can't be import because of the error in the subject of this thread.

[ovirt-users] hosted-engine deploy seems to be failed, but it is not
Hi folks, A while ago I installed oVirt 4.2 on my CentOS 7.5 server. It is a single node. Everything is working, I can deploy VM's, etc. But it look likes that the hosted-engine is partly installed or something. [root@s01 ~]# hosted-engine --vm-status It seems like a previous attempt to deploy hosted-engine failed or it's still in progress. Please clean it up before trying again [root@s01 ~]# Any suggestions? Thanks!
