Experience with VMware

1, supported guest OS: VMware supports the following guest OS: MS-DOS, Win3.1, win9x/me, WinNT, Win2000, WinXP, Win.net, Linux, FreeBSD, NetWare6, Solaris x86. Unsupported Guest OS: BeOS, IBM os/2 and Os/2 Warp, Minix, QNX, SCO Unix, UnixWare. 2, VMware Simulation of hardware VMware's analog hardware includes motherboards, memory, hard disks (IDE and SCSI), Dvd/cd-rom, floppy, NIC, sound card, serial port, and USB port. VMware did not simulate the video card. VMware provides a software package called Vmware-tools for each guest OS to enhance the display and mouse capabilities of the guest OS. 3, VMware Analog hardware is a fixed model, and the actual hardware regardless of the host OS. For example, installing Linux with VMware on a single machine can run the entire Linux copy into other VMware machines without having to install it again. 4, VMware can use the ISO file as a CD. For example, download the Linux ISO file from the Internet, do not need to dial, can be directly installed. 5. VMware provides three options for the operation of the guest OS: (1) Persistent Any actions you make in the Guest OS run are saved for immediate filing (2) undoable Guest OS shutdown asks if you want to save your actions (3) Nonpersistend Any action done in the Guest OS run, after shutdown, is not done. If you want to do software testing or testing, this is very useful function, you can enjoy the play, put The Guest OS is not afraid to die unlimited time. 6, VMware's two kinds of network setup mode: (1) Bridged Way In this way, the guest OS IP can be set to the same network segment as the host OS, the guest OS is equivalent to a machine in the network, and other machines in the network can access the guest Os,guest OS can also access other machines in the network, of course, with host Bidirectional access to the OS is also not a problem. (2) Nat Way This approach also enables two-way access to the host OS and the guest OS. However, other machines on the network cannot access the Guest os,guest OS to access other machines within the network through the host OS using the NAT protocol. NAT Way IP Address configuration method: The Guest OS first uses DHCP automatically obtains the IP address, the Host OS's VMware services will assign an IP to the guest OS, then if wants to start each time to use fixed IP words, in guest This IP can be set directly in the OS. Generally speaking, the bridged way is most convenient and easy to use. However, if the host OS is Win2000 and the network cable is not plugged in, it is likely to be unavailable (most machines with a PCI network card), and this is only Nat. 7, VMware uses the host OS files to simulate the guest OS's hard drive. A guest OS's hard disk corresponds to one or more files in the host OS. If you write 100M files to the guest OS, the virtual hard disk files in the Host OS increase by 100M. Deleting this 100M file in the guest OS will not reduce the virtual hard disk files in the Host OS. The next time you write a file to the guest OS, this part of the space can continue to be used. The Vmware-tools also provides shrink functionality to instantly release unused space, reducing the capacity of the virtual hard disk files in the host OS. In order to reduce the waste of hard disk space, avoid frequent use of shrink, a better way is to hang another hard disk in the guest OS to store infrequently used files, such as installation files, and then you can repartition the hard disk. 8, Vmware-tools Vmware-tools enhances the display and mouse function of the guest OS. Vmware-tools with VMware. Install the guest OS, VMware's status bar has a word that vmware-tools not installed, mouse Click this sentence can be installed vmware-tools. can also be installed through the menu: Settings-> VMware Tools Install If the guest OS is Windows,vmware-tools will automatically install, if it is Linux, after installation, vmware-tools installation files will be mounted to the CD drive (is the virtual mode, the CD drive does not have a CD-ROM), into the CD drive mount point , the file copy out of the installation can be. VMware does not provide openlinux for some guest OS, such as Solaris x86, NetBSD 1.x, OpenBSD 2.x, and Caldera Vmware-tools 1.3. 9, in VMware installed Linux, do not use graphics mode installation, to be installed in text mode. When you install to the configuration Xserver, you can choose the default configuration, and the installation error will not be ignored. After installation, do not start X, first install a good vmware-tools, then boot x. 10, if not using a sound card, do not add a sound card in VMware, the sound card has a little impact on performance. 11, if the light drive is not often used, you can cancel the optical drive of the Connect at Power on option, when needed, the optical drive can be "hot plug".
