Hi, on F7,,I have vmware-server-1.0.3 installed {vmware-any-any-109},
and have a winXP guest vm. I start the vm when I boot my laptop.
I bit later I return to the guest, and find it unusable - clicking anway
doesn't seem to be noticed, or takes a stupid {minutes++} amount of time
to happen. The guest has the vmware-tools installed.
Meanwhile the disk is being continually accessed, and top shows that
updatedb, and then other tasks are being run. Having these affect the
normal operation of a vm guest isn't acceptable - especially since the
indexing etc takes about 10-15 minutes, leaving the vm unusable.
Is there a way to config it so that anacron doesn't instigate stuff
while a vm guest is running ?
Is there a way to automatically pause the processes started by anacron
when a vm guest is brought to the foreground ?
While disabling the anacron service would work, what I am after is
letting it be enabled, but play nice with the other guys - the work I
need to do.

You might want change the hour of the updatedb process in crontab?
Thanks for your response, Manuel,
Would that help ?
By default anacron is set to be an active service, and it:
Unlike cron(8), it does not assume that the machine is running
continuously. Hence, it can be used on machines that aren't running 24
hours a day, to control daily, weekly, and monthly jobs that are usually
controlled by cron.
My reading of the config suggests that after (65..75)+random(68) minutes
after the machine boots up, it will execute the following if they
haven't yet been run at the scheduled time=04:00.
000-delay.cron cups mlocate.cron rpm
0anacron logrotate prelink tetex.cron
0logwatch makewhatis.cron readahead.cron tmpwatch
It isn't that I want to disable these things from running altogether,
just that they should only run if my machine is really idle - not just
available CPU cycles {since most don't use much CPU}, but when there is
nothing else wanting to do disk access. If the machine gets turned on at
09:00, then these utils start to do their thing while I am trying to use
the machine an 1.5 hours later.
For CPU, nice can be used to assure processes that need real-time
response get CPU. Is there _nice_ for disk access ? {an aside - is there
nice for network access ?}
