Click the Security tab, select the Promiscuous Mode check box, and select Accept from the dropdown menu. m. Click OK, and then click Close. 7 of 16

8 2.3 Virtual Machine Network If you plan to use this VM as a CMC, do not configure a virtual machine network. Use the VM network to capture traffic from virtual systems. If you are not planning on capturing virtual traffic, you may skip to section 2.4 Playback Network. Create a virtual machine network a. Connect to the ESX server using the vsphere client. b. In the left pane, select the target ESX server. c. In the right pane, open the Configuration tab. d. Select Hardware > Networking. e. For vswitch1, click Properties. f. Click Add, then select Virtual Machine. g. Label the network VM Network. h. Select Next, then Finish. i. On the Ports tab, select Virtual Machine Network, then click Edit. j. Click the Security tab and select the Promiscuous Mode check box. k. Select Accept from the drop-down menu. l. Click OK, and then Close. 8 of 16

9 2.4 Playback Network If you plan to use this VM as a CMC, do not configure a playback network. Use the playback network to play back traffic from either virtual networks or physical networks. If you are not planning on playing back traffic for either type of network, you may skip to Section 3: Virtual Appliance Installation. Create a playback network a. Connect to the ESX server using the vsphere client. b. In the left pane, select the target ESX server. c. In the right pane, click the Configuration tab. d. Select Hardware > Networking. e. Click Add Networking. f. Select Virtual Machine, then click Next. g. Select Create a virtual switch. h. Select an available VM NIC and click Next. i. Label the network Replay Network and leave the VLAN ID field blank. j. Click Next, then Finish. k. For vswitch1 click Properties. l. Select Replay Network, then click Edit. m. On the Security tab, select the Promiscuous Mode check box. n. Select Accept from the drop-down menu. o. Click OK, then Close. Playing back traffic to the same virtual or physical network that you used for capture can create network storms. Use extreme caution when playing back network traffic. 9 of 16

10 3 Virtual Appliance Installation These installation steps assume that you have downloaded and extracted the virtual appliance from Blue Coat Systems.

12 3.3 Add Indexing and Capture Virtual Disks Except for the ESX trial version, the Security Analytics Virtual Appliance includes one virtual hard disk, which is the system virtual disk. To function properly, the Security Analytics Virtual Machine requires two additional virtual disks for indexing and capture. If you have deployed the ESX trial VM, the capture and indexing virtual disks have already been configured for you. It is highly recommended that you place the capture virtual disks on a logical unit comprising at least three (3) physical hard drives to achieve optimal capture performance. It is also recommended that you not share the logical unit with any other virtual machines to avoid excess read/write overhead. Add indexing and capture virtual disks on ESX a. On the vsphere client, select the virtual machine and click Edit Virtual Machine Settings. b. On the Hardware tab, click Add. c. Select Hard Disk and click Next twice. d. For Disk Size, consult the tables in Appendix: Virtual Machine Sizing for the size of the capture virtual disk(s).

If you have any questions or need further assistance, contact Blue Coat Support. Contact Information: bluecoat.com/support/technical-support/contact-service-support BlueTouch Online: bto.bluecoat.com Cannot Connect to the UI 1. Verify that you can ping the host IP address from the virtual appliance. 2. Verify that the virtual appliance has a valid gateway route: [prompt]# route 3. Restart the network services: [prompt]# sudo service network restart 4. Verify that the network interface of the machine where the virtual appliance is running is a bridged network interface. Refer to the VMware documentation for information on how to configure the network interfaces. Cannot Capture Data 1. Verify that IP has been disabled on the physical interfaces that capture data. 2. Verify that you have modified the virtual interface to operate in promiscuous mode. 3. Confirm that you have added index and capture virtual disks before powering on the VM for the first time. If this was not done, delete the VM and start over. Networking Not Working Properly If networking is not working properly within the guest OS VM e.g., you do not have a valid routing table, or you did not obtain an IP address from your DHCP server you should try restarting the networking service at least once to resolve the issue: [prompt]# sudo service network restart 14 of 16

15 64-bit Host Operating System with Virtual Technology The Solera Virtual Machine requires that the server's CPU be both 64-bit and VT capable. More information about running a 64-bit guest OS on VMware platforms can be found in Article : "Hardware and Firmware Requirements for 64-bit Guest Operating Systems" in the VMware Knowledge Base ( If you are uncertain of your ESX server or host computer s 64-bit compatibility, you can obtain a processor check utility from VMware from Article , referenced above. Error Message This kernel requires an x86 64 CPU, but only detected an i686 CPU. Unable to boot please use a kernel appropriate for your CPU. You attempted to start the guest OS VM on an ESX server or host computer that is not 64-bit and VT capable. Install your VMware ESX server or on a computer that is both 64-bit and VT capable. Error Message You have configured this virtual machine to use a 64 bit guest operating system. However, 64 bit operation is not possible. This host is VT capable, but VT is disabled. You attempted to start the guest OS VM on an ESX server or host computer that is both 64-bit and VT capable, but whose VT settings are disabled in the BIOS. This is usually because VT has been disabled in the BIOS/firmware settings, or the ESX server or host computer has not been power-cycled since changing this setting. 1. Verify these BIOS/firmware settings: enable VT and disable trusted execution. 2. Power-cycle the ESX server or host computer if you changed either of these BIOS/firmware settings. 3. Power-cycle the ESX server or host computer if you have not done so since installing VMware. 4. Update the host computer's BIOS/firmware to the latest version. For more details, see Article , referenced above. 15 of 16
