clock setting must be enabled (set to 1). Otherwise, it will continue to synchronize its

time with its host.

Procedure 6.1

Viewing the Independent Wallclock Setting

In the virtual machine environment, enter

cat /proc/sys/xen/independent_wallclock

•

0 means that the virtual machine is getting its time from the host and is not using

independent wallclock.

•

1 means that the virtual machine is using independent wallclock and managing

its time independently from the host.

Procedure 6.2

Permanently Changing the Independent Wallclock Setting

Edit the virtual machine’s /etc/sysctl.conf le.

Add or change the following entry:

xen.independent_wallclock=1

Enter 1 to enable or 0 to disable the wallclock setting.

Save the le and reboot the virtual machine operating system.

While booting, a virtual machine gets its initial clock time from the host. Then, if

the wallclock setting is set to 1 in the sysctl.conf le, it manages its clock time

independently and does not synchronize with the host clock time.

Procedure 6.3

Temporarily Changing the Independent Wallclock Setting

Enter the following command:

68 Virtualization with Xen

1 2 ... 69 70 71 72 73 74 75 76 77 78 79 ... 97 98
