[eth0 hardware hang]

Ok, thank you for the advice

[eth0 hardware hang]

Ahh, sorry, I am new to unRaid and I do not come to this part until now and I assumed that use VirtualBox :D, my bad.

But it seems that there are the same limitations

[eth0 hardware hang]

All my VM's from above disertation are on a bare metal unRaid machine.

I only compared unRaid OS with Synolgy DSM OS that both use Virtual Box.

Who can think to virtualize inside another virtualized enviroment :))))

I talking about unRaid.

Virtual box is used in unRaid and Synology DSM, so the limitations are the same.
The only difference is that Synologi DSM does not let you allocate virtual cores more than double the threads of the processor.

I kill three of the VM's, and now is working OK without any hang, I see that there is a limitation of maximum two virtual cores per processor thread, that I see it explicitly documented on Synology DSM that use the same VirtualBox and does not let you allocate more than double the number of threads of the processor, so the maximum viable allocated cores in my case is 8 virtual cores on a 2 core 4 thread procesoor.

About the wrong expectation is that I wondered if I can fool the machine to do this work until the new hardware will come from the store.

Ehh, my bad, I will change the status of this thread to "other" and "solved", and remain for others to see like documentation

[eth0 hardware hang]

Ehh, yes is a bit too much (is a 4 thread core) , but does not eat to much core power and each VM is configured with 512MB of ram and one virtualized core.

The problem is not the core, is the network that is hanging and the kernel does not know what to do with this hanging, or something is wrong with virtualbox network driver.

I watched the LED's on the network, and when the network is dead , for three seconds all status LED's on the network card are off, and 7-8 seconds light up and show network activity, and continue to do this infinitelly, but the rest of the machine work well the HDD led show normal activity.

Tomorow I will receive the new hardware for this machine, a Rizen 7 1700 (8 core, 16 threads) and I will see the comportament of the machine.
