Strangely I have a virtual machine that keeps constantly freezing for some seconds or minutes.
On the OS side, the CPU and memory used are quite low. On VMWare side, it's the same, the machine never uses more than 50% CPU. All other machines on the same VMWare ESXi server are running perfectly fine.
After hours of trying to figure out what could be the cause of this problem I decided to ask if anyone had an idea ? Of course I also searched intensively the web, and a colleague was also unable to find any hint.
What's difficult is that it can be anything, either on Windows, either on VMware site, as I don't see any graphic or number showing any problem.
Thanks a lot in advance for any hint or help !
P. S. Versions details : Guest OS : Windows XP, running "Symantec Endpoint Antivirus Console" VMWare ESXi 4.1.0
Check the vmware syslog, an easy way is move the /scratch/log in advanced configuration to a datastore then download the syslog using the file manager in vsphere.
Can also use the syslog collector http://blogs.vmware.com/vsphere/2011/07/setting-up-the-esxi-syslog-collector.html
If you have guest specific problems and the hosts are fine, then it points towards a guest os software problems and nothing to do with vmware. Read the event logs on the guest operating systems for errors that might indicate driver problems. Consider upgrading the vm version and vmware tools. If it is just a symantec console then you can build a new server and reinstall the software and readd all the clients back in if the problem persists.
