Although I am not running QMT on a ESX host, I have had several other ESX CentOS VMs that suffer from clock tick problems. I highly recommend installing the VMware tools. Installing those tools have resolved the problem every time for me.
# mkdir /mnt/cdrom Open the VMware Infrastruce Client, right-click your VM, and select "Install/Upgrade VMware Tools". # mount /dev/cdrom /mnt/cdrom # rpm -Uvh /mnt/cdrom/VMwareTools-3.5.0-64607.i386.rpm (or whatever version you have) REBOOT Whenever you replace/update your kernel, you'll have to do the following: # /usr/bin/vmware-config-tools.pl # /etc/rc.d/init.d/network stop # rmmod pcnet32 # rmmod vmxnet # depmod -a # modprob vmxnet # /etc/rc.d/init.d/network start There is a wonderful white paper about VMware time keeping at: http://www.vmware.com/pdf/vmware_timekeeping.pdf Sincerely, -- Joseph Lundgren Systems Engineer Peak Internet, LLC joseph.lundg...@peakinternet.com -----Original Message----- From: Michael Colvin [mailto:mcol...@norcalisp.com] Sent: Wednesday, October 07, 2009 9:38 AM To: qmailtoaster-list@qmailtoaster.com Subject: [qmailtoaster] QMT on VMWare ESXi Is anyone running the QMT iso on a VMWare VM? I had one set up just to play with, but noticed the clock keeps horrible time. I was able to adjust the "ticks" to keep it more accurate, along with an hourly sync, but this seems ridiculous. From what I've found, it's an issue with CentOS in a VM, but I've got CentOS running in a VM for a PBX, and it seems fine. This is the only time I've ever had an issue with the system/hardware clock drifting dramatically in a VM. There are also other VM's on this physical server that keep sync fine... Michael J.
