Creating and Deploying Virtual Machines.

Question 1

VM Hardware Categories.

Answer 1

1. CPU
2. Memory.
3. Disk.
4. Netork.

Question 2

VM Hardware Versions.

Answer 2

Table 10-2.

Version 11:
1-128 vCPUs for SMP. (License-level dependent).
4 TB Memory.

Versions 9-11:
Hot add for:
Disk, Ethernet, SCSI, USN, Memory, CPU.

Question 3

VMWare Tools.

Answer 3

1. SVGA: (?)
2. vmxnet-vmxnet3 vNIC Drivers:
3. Balloon Driver for Memory Management.
4. Sync Driver for quiescing I/O: vMotion, Storage vMotion, snapshots.
5. Improved Mouse Support:
6. VM Heartbeat: HA VM Monitoring.
7. Time Sync: Sync VM time with host.
8. Ability to shutdown VM: Shutdown gracefully without logging in.

Question 4

Access VM Console.

Answer 4

1. Right-click, open console.

2. Summary tab.

Question 5

VM Clones Requirements for DirectPath I/O Passthrough.

Answer 5

1. Enable card for DirectPath I/O Pasthrough.
2. Configure connection to be enabled as VM hardware.

Requirements:

1. VM hardware must version 7 or later.
2. Host must have Intel VT-d or AMD I/O enabled.
3. VM cannot be connected to more than 8 devices ata time.
4. PCI devices must be connected to device and marked for Passthrough.

Enabled DirectPath I/O Pasthrough: VM cannot use vMotion, DRS, HA, snapshots, FT, and hot add. Should be seen as one-off setting.

Question 6

Configure/Modify vCPU Resources.

Answer 6

Obtain one “core’s worth” of processing power for each vCPU.
Example: Host has Quad Core 2.5 GHz processor. You will obtain an max of 2.5 GHz processing power. per vCPU. VMKernel will load-balance over multiple cores, but 2.5 is numeric result.

Should not create VM with more than one vCPU unless application requires more than one.
Pg. 409.

Hot add vCPU:

1. Guest OS must support hot-add.
2. Must select “Enable CPU to Hot Add” with VM powered down.
3. Some guest OSes will need to reboot/some won’t.

Question 7

Configure/Modify Memory Resources.

Answer 7

During installation of OS on web client, amount of RAM will be suggested but can be configured.

Not a guarantee of memory to the guest, but guest how much guest thinks it has.

Hot-add:

1. Guest OS must support hot-add.
2. Must select “Enable Memory to Hot Plug” with VM powered down.
3. Some guest OSes will need to reboot/some won’t.
