Udv,
Miert van szukseg vmware alatt a vmem fajlokra? (amelyek ugytunik IO problemakat okoznak)
Amit eddig tudok:
>>>What exactly is stored in the .vmem-files?
Guest memory. (..ez miert is jo ?!)
>>>How often does the information change in those files?
Continuously. When stored on disk, kernel updates file on disk whenever it feels it shoud do such.
>>>Since I now moved them to a memory based tmpfs, each VM now uses twice the amount of RAM.
I personally would highly discourage use of tmpfs (or any ram based filesystem) for *.vmem. Your machine may deadlock when you'll put it under memory stress.
>>>It is also possible to switch the usage of .vmem-files off entirely?
No, guest memory must be backed by something, and it does not matter whether it is swapfile or file on filesystem. (....Miert?)
On Windows problem is quite simillar, but 'mainMem.useNamedFile = "FALSE"' on Windows will do almost what you want as Windows provide shareable anonymous memory blocks, at the cost that suspend/resume will be much slower. On Linux it will just use deleted file in /tmp instead of file in directory with VM, so there are benefits only if /tmp is much faster than directory with VM (like if you run VM from USB or from network)
