These days I see 90% hosts who have been in industry offering either OpenVZ and/or KVM where as the new providers don't even consider VMware (I am talking about the free version which is called vSphere hypervisor) or XEN HVM. For quite sometime I have used VMware to make VMs on one of my dedicated servers for personal use & found it to be very reliable & stable also XEN HVM is most mature bare metal hypervisor & I always liked whenever I ordered a XEN HVM vps but I am surprised at lack of love for them.
It might be just me only but I always found Windows running much stable & smooth on VMware & XEN HVM as compared to KVM.
What do you think is it just because KVM is backed up by Red Hat & out of box kernel support that every host is preferring it or is there something really wrong with VMware & XEN HVM? Remember most of the big & well known cloud providers are either using XEN or VMware.
Note: I like KVM, XEN & VMware(all 3 of them)----all of them have their pros & cons though but still I am just curious about lack of love for VMware & XEN HVM.
