Typical Restart

Setup the network cards Network “Kralicek azurit” has IP 10.2.2.x, Mask 255.255.0.0, GW 10.2.0.1, DNS1

195.113.19.71, DNS2 195.113.19.77 Network “Virt mgmt” has IP 10.250.x.250, Mask 255.255.255.0 Use MAC for network detection

Enable remote access Access from anywhere using RDP to acheron.ms.mff.cuni.cz:112xx (e.g.

Mount VC image

VMware vSphere ESXi installation

Deploy template vsph55templ VM name VSPxy Start VSPxy Install ESXi

Ignore warning “HW virtualization not available” Press F2 and login Select “Configure management network”->”Network adapters” Check the right network adapter (use MAC) connected to the

“Virt mgmt” virtual network and confirm Select “IP configuration”, choose “Set static IP…”

IP 10.250.x.y, mask 255.255.255.0, GW 10.250.x.250 Select “IPv6 configuration” and disable IPv6
