Hello, I am currently evaluating kvm for using it for an application where correct time is absolutely critical. We therefore normally use NTP on these machines to synchronize them with GPS time. For a virtual machine in my eyes that means, the host should be synchronized and the guests just use that time.
My test setup is on Kubuntu 7.04 with a minimal Kubuntu 7.04 guest. I am using its "linux-virtual" kernel package, so I believe I should be correctly paravirtualized. Now what I see with respect to system time, is that the time is lagging behind in the guest. Abount 1 minute after 20 minutes, and 1 second only a few seconds after a successful ntpdate to the hosting machine. My guess, that shows how little the host is used otherwise. So in FAQ and Wiki I didn't find how to make the guest use host time. Is that possible at all? For VMWare it is said that clock=pit would help, but that seemed to be no change. Can you please point me to what to do? Best regards, Kay Hayen ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
