Is it possible to match the CPU model of SolusVM VPS to the CPU of the host node?
Yes, it is possible:
Login to SolusVM administrator area.
Open Virtual Servers > VPS > Settings > CPU.Changing CPU model
In Model list select host-model or host-passthrough.Option details
Host-passthrough - with this option host CPU is emulated/passed to VPS without any modifications, making this option best for performance, however, VPS will be "bound" to this specific CPU, breaking VPS if it was migrated to a host-node with a different CPU.
Host-model - matches host CPU with a predetermined list of CPU configuration, making it compatible for another host in case of migration, but providing slightly lesser performance gain.
Reboot VPS via Virtual Servers > VPS > Reboot.
