CHAPTER 1 Introduction to VMware ESX Server
35
The following table includes some general troubleshooting information.
Be sure there is sufficient
swap space for your guest
operating system.
For resource management purposes, ESX Server may increase the
memory utilization within a guest operating system. Therefore, it is
important to ensure that the guest operating system has sufficient
swap space.
Add additional swap space in the guest operating system, equal to
the difference between the virtual machine's maximum and
minimum memory sizes.
See Admission Control Policy on page 405.
Remove any unnecessary
programs or services from
your service console.
Do not run the X Window system in your service console.
Use SNMP to watch memory,
resource usage, and
workloads on ESX Server and
its virtual machines.
See Using SNMP with ESX Server on page 265.
Problem Suggestions
Can’t start a virtual machine. Check permissions on the virtual machine configuration file and on
the virtual disk. See Setting Permissions for Owners of Virtual Machines
on page 166.
Check that there is enough memory to power on this virtual
machine. See Sizing Memory on the Server on page 424.
Check that there is enough unreserved swap space. For more
information, see Swap Space and Guest Operating Systems on
page 408
.
Check that the virtual disks are in a VMFS volume. If the virtual disk
file is from VMware Workstation or VMware GSX Server, be sure the
virtual disk has been properly imported, through the management
interface, into ESX Server.
See Migrating VMware Workstation and
VMware GSX Server Virtual Machines on page 67.
Can’t connect to the VMware
Management Interface.
Check to see if there has been a loss in IP connectivity.
Check that the NIC duplex or speed matches with the Ethernet
switch.
Check that the service console is not swapping.
Check that the root file system has available disk space.
