McAfee Deep Defender 1.5, 1.0.1, 1.0
This article contains important information about Deep Defender Virtual Machine (VM) support. Consider the following points if you are planning to deploy Deep Defender:
- You cannot install Deep Defender inside a VM
Deep Defender requires the Virtualization Technology (VT) available on Intel CPUs. This is only available on the physical system or the hardware, and not inside a VM.
- You cannot run 64-bit VMs when Deep Defender is installed on the physical machine
Deep Defender requires the VT available on Intel CPUs. 64-bit VMs also require this hardware virtualization to run. Therefore, if Deep Defender is installed and running, the hardware virtualization is not available to other applications.
- Performance degradation inside a VM when Deep Defender is installed and running on the physical machine
Your experience inside a VM might be impacted due to performance degradation. This degradation might manifest itself as spikes in CPU utilization or display 'jitters' inside the VM.
NOTE: During testing, the performance on the host was not affected in the same way.
- If you create a new VM with Virtual PC 2007, it is very slow when Deep Defender is installed and running on the physical machine
Creating a new VM with Virtual PC 2007 might be extremely slow, and at times the process might stop responding.
NOTE: During testing, this was consistently observed on multiple systems. McAfee is currently investigating this issue, and this article will be updated when additional information becomes available.
- The previously saved state of a VM Guest might not be restored after Deep Defender is installed on the Host
Deep Defender utilizes and modifies the CPU VT feature in the Physical Machine, such that the previously saved states of VMs are no longer valid after you install Deep Defender. You have to restart the VM and clear the previously saved states to run them.
- Windows XP Mode VM might sometimes report an error on creation
Windows XP Mode VM might report an error on creation if Deep Defender is installed on the physical system. This was observed in various scenarios during testing.
- VMs created with Parallels Desktop 4.0 for Windows & Linux cannot run when Deep Defender is installed on the physical machine
Parallels Desktop 4.0 requires hardware virtualization to run VMs. If Deep Defender is installed and running, the hardware virtualization is not available to other applications.
NOTE: Parallels Desktop 6.0 provides software-based virtualization and has been found to be fully compatible with Deep Defender after testing by McAfee.
- Systems running Deep Defender 1.0 restart if you run a VM from VMware Workstation 8.0 or VMware Player 4.0
NOTE: This issue does not occur with Deep Defender 1.0.1 or Deep Defender 1.5.
During testing, McAfee observed that the system restarts if you try to run a VM from VMware Workstation 8.0 or VMware Player 4.0 when Deep Defender is installed and running on the physical machine. McAfee is currently investigating this issue, and this article will be updated when additional information is available.
- The system generates a BSOD when you start or create a guest VM with Parallels Desktop 6.0 on certain systems running 32-bit Windows 7
During testing, McAfee observed a BSOD with Bugcheck IRQL_NOT_LESS_OR_EQUAL (a) when starting a guest VM on certain systems running 32-bit Windows 7. However, this was not observed on other systems running 64-bit Windows 7.
- Very slow performance when installing a guest OS via VMware Player4 on a 32-bit OS, with Deep Defender installed
This issue was only seen on a 32-bit OS.
NOTE: The following points are applicable for the following VM versions, unless a specific version is explicitly identified:
- VMware Workstation 7.1.4
- VMware Workstation 8.0
- VMware Player 3.0.1
- VMware Player 4.0
- VMware Server 2.0
- Virtual PC 2007 SP1
- Virtual PC 2007
- Virtual PC XP Mode
- Oracle Virtualbox 4.1.4-74291
- Parallels Desktop 4.0.6630.449744
- Parallels Desktop 6.0
- Microsoft Virtual PC XP Mode only supports a 32-bit Virtual Machine. For additional information, go to: http://www.microsoft.com/windows/virtual-pc/support/faq.aspx.
- Virtual PC only supports 32-bit Virtual Machine Guests. For additional information, go to: http://support.microsoft.com/kb/831461.
- Software-based virtualization is utilized when hardware virtualization is not available. All the above-mentioned versions of VM Applications except Parallels Desktop 4.0 use this feature.
