Is KVM faster than VMware?
In terms of speed, KVM runs applications at near-native speeds, faster than other industry hypervisors, according to the SPECvirt_sc2013 benchmark. Hypervisors use different methods to communicate with the physical hardware of the host. … Cost is a key differentiator between KVM and the VMware virtualization solutions.
Is KVM Type 1 or Type 2?
Basically, KVM is a type-2 hypervisor (installed on top of another OS, in this case some flavor of Linux). It runs, however, like a type-1 hypervisor and can provide the power and functionality of even the most complex and powerful type-1 hypervisors, depending on the tools that are used with the KVM package itself.
How do I check if IOMMU is enabled?
With 4.11 linux kernel version iommu_device_sysfs_add is referenced in many IOMMU drivers, so checking /sys/class/iommu is better (more universal) way to programmatically detect enabled IOMMU than parsing dmesg output or searching in /var/log/kern.
