U disk for our daily life is a very important thing, help us save important files, is also a good transmission work, when the need to transfer files, we can copy the file to a U disk, and then copy to another computer, so the U disk for our life is vital. But now sometimes we often encounter some small difficulties, that is, when copying files to a U

for work, I just need to create a virtual Windows 2000 In ubuntu. I tried a Windows 2000 virtual machine a few days ago, and the speed was quite fast. After all, it was something I had done seven years ago and it didn't have high performance requirements. Although the performance of the virtual machine is inferior to that of the real machine, the progress of the hardware is negligible. Tu7.04 was finally

A lot of information has been found to find a solution at last.The virtual disk (. vmdk) itself has a

Thin provisioning (thin):Thin provisioning is the amount of storage that is used now, regardless of how large the disk is allocated, and how much is used. When the client has input and output, Vmkernel first allocates the required space and clear 0 operations, that is, if the use of thin configuration when there is IO need: Wait for the allocation of space and zeroing, these two steps to complete before the operation, for the IO called frequent applic

, and in the pop-up Properties dialog box, select Disabled "Report Errors" can be disabled by the radio box. 24, turn off the unused equipment: Windows XP is always as much as possible to install the computer drivers and management of all devices, which will not only slow down the speed of system start-up, but also caused a large number of system resources occupied. In this case, you can in the Device Manager, deactivate devices that are not commonly

In the implementation of individual projects, often have colleagues or customers ask "VMware virtual machines have three provisioning, thick provisioning delay to 0, thick provisioning format, which is good for thin provisioning", depending on the specific circumstances, from different points of view, the answer is to choose the most appropriate, not the best. A while ago, I studied Wang Chunhai's blog, "Virtual
