RHEL5.4 why the xm console does not respond and Its Solution

The strange thing is to connect to the Guest console according to the official RHEL file, but the system is like a dead fish, no response !! Check the/var/log/message of Guest and find that there is no console. After one afternoon, it seems that the security permission cannot allow the console to log on !! However, this should be because the console of the root user should not respond to the Guest. Check whether the Guest still needs to be set. Otherwise, the command xm console alone cannot be logged in !! 1. Specify the console value in/boot/grub. conf "console = tty0 console = xvc0" [root @ benjr ~] # Vi/boot/grub. conftitle Red Hat Enterprise Linux ES (2.6.9-78. ELxenU) root (hd0, 0) kernel/boot/vmlinuz-2.6.9-78.ELxenU ro root = LABEL =/console = tty0 console = xvc0initrd/boot/initrd-2.6.9-78.ELxenU.img2. the/etc/inittab system cannot use comport to log on to the system by default. Therefore, modify/etc/inittab, [root @ benjr ~] # Vi/etc/inittabco: 2345: respawn:/sbin/agetty xvc0 9600 vt100-nav3. /etc/securetty root cannot use comport to log on to the system due to PAM restrictions. Therefore, modify/etc/securetty: [root @ benjr ~]. # Vi/etc/securettyxvc0 [root @ benjr ~] # Xm listName ID Mem (MiB) VCPUs State Time (s) domain-0 0 1231 4 r ----- 150.1rhel4.6 2 255 1-B ---- 0.1rhel5 4 511 1-B ---- 2.2 you will see all the currently running Guest. [root @ benjr ~] # Xm console rhel4.6. If the settings are correct, you can see the console screen !! This problem can be solved as described above. Author pengcz
