Hosts file entries for multiple domains on VPS?

Question

mydomain is the main domain (in Plesk, Media Temple MT VPS), and under that are several Wordpress sites, like mysite1.com, mysite2.com, etc.

Problem is that I get lots of these errors in httpd's error_log:

[error] [client 127.0.0.1] script '/var/www/html/wp-cron.php' not found or unable to stat

wp-cron.php does exist at the html root in all the Wordpress installs.

I've found hints elsewhere that these errors may have something to do with my /etc/hosts file. This is the hosts file:

127.0.0.1 mydomain.com mydomain localhost localhost.localdomain

Question: do I need to add mysite1.com, mysite2.com, etc., to the hosts file so they resolve and can find the wp-cron.php file?

Edit: found the answer after much Googling. Seems that there are two issues: the hosts file and the fact that MT VPS overwrite the hosts file on each reboot. So the hosts file should look like this for multiple domains on one server:

127.0.0.1 localhost localhost.localdomain
xxx.xxx.xxx.xxx  yourdomain1.com yourdomain1 yourdomain2.com yourdomain2

And those lines must have a few blank lines above the in the hosts file, or they will get overwritten each reboot. See http://bradt.ca/archives/fix-wordpress-missed-schedule-error-on-media-temple-dv-plesk/

Solution

Found the answer after much Googling. See edit above.
