I am part of an organization in which there is competition among some very competent people regarding whether cross-browser behavior is checked for JavaScript intensive web applications on virtual machines (for IE6 / 7/8, FF2 / 3, Chrome on XP / Vista / 7) is reliable. This uses the VMWare server on the Linux box host.
While there are few revealed discrepancies, there are times when it turned out to be difficult to say whether this is a virtualization product or just different machine configurations.
My question is to the community, what do people experience with this? Is there any credibility in the claim that VMs are nonconformities, or are they generally reliable? Can we trust them?
If the virtual machine is running a normal OS, there should be no problem with its browser.
It is possible that differences in rendering and performance may be noticeable, but you should check this out anyway.
VM is the best way. Other options, such as multiple differences in IE, are much more common. Personally, we use the Virtual Block
