    Hello,

    I have created sucessfully a fully virtualized guest OS (RHEL 5) using virt-install.
    I used a custom ISO image as the source to boot from.
    It works.

    Then I try to creating a second fully virtualized OS (RHEL 5) as above using the same method using virt-install.
    During the creation of the second guest OS's HDD image file, it caused the host (the physical machine) RHEL 5 to reboot.

    I also try using virt-manager to create the second fully virtualized OS. The procedure also caused the physical machine to reboot.

    I have attached the various files for your reference.
    According to line# 108 of xend.log, it says the following :
