#oVirt Storage and Network

Revised: April 8, 2016

Article 10 of the Open Source Virtual Data Center Series

##Storage When creating storage domains, you must create a Data domain, first. You will need at least one Data domain and one ISO domain.

###Data Storage Domain The Data Storage domain is used to store virtual machines files.

  1. Connect to oVirt and authenticate to the Administration Portal
  2. Select the "Storage" tab
  3. Select "New Domain" button
  4. Data Center: Default
  5. Domain Function: Data
  6. Storage Type: NFS
  7. Use Host: hosted_engine_1 (or _2)
  8. Name: datadom
  9. Description: Data Storage Domain
  10. Export Path: nasv.mydomain.net:/mnt/r10vol/data
  11. Select "Custom Connection Parameters"
  12. NFS Version: V4
  13. Select "OK" button

###ISO Storage Domain The ISO Storage domain is used to store installation ISO files.

  1. Select "New Domain" button
  2. Data Center: Default
  3. Domain Function: ISO
  4. Storage Type: NFS
  5. Use Host: hosted_engine_1 (or _2)
  6. Name: isodom
  7. Description: Data Storage Domain
  8. Export Path: nasv.mydomain.net:/mnt/r10vol/iso
  9. Select "Custom Connection Parameters"
  10. NFS Version: V4
  11. Select "OK" button

A summary of storage domains can be viewed anywhere you see a Storage tab or by selecting Storage under any cluster. Note the "hosted_storage" domain. It is the domain we specified during the --deploy and where the oVirt Engine Appliance is installed. I choose to separate it from other virtual machines.

##Network

###Create Networks

  1. Connect and authenticate to oVirt
  2. Select "Data Centers"
  3. Select "Default" or your data center
  4. Select "Networks"
  5. Select "New" button
  6. Data Center: Default
  7. Name: infra101
  8. Description: Infrastructure Network
  9. Network Label: infra101
  10. Enable VLAN tagging: 101
  11. Note VM network is enabled
  12. Select "OK" button

Repeat for sec121, intra131, dmz201, and dmz211.

Result with

ovirtnetworks

###Create Network Bonds

Warning!

When working with the bond used by oVirt Appliance on the Compute host it is running, be careful. As a precaution, configure the bond on the other Computer host. When complete, enter maintenance mode for the Compute Host in use by the appliance to live migrate it then configure bond.

  1. Connect and authenticate to oVirt
  2. Select "Data Centers"
  3. Select "Default" or your data center
  4. Select "Clusters"
  5. Select "Default" or your cluster
  6. Select "Hosts"
  7. Select "hosted_engine_1"
  8. Should default to "Hosts" tab otherwise select "Hosts"
  9. Select "Network Interfaces" tab
  10. Select "Setup Host Networks" button
  11. Right-mouse click "enp6s0f0"
  12. Select "Bond enp6s0f0 with" and "enp6s0f1" which creates "bond0"
  13. Accept the defaults and select "OK"
  14. Right-mouse click "eno1"
  15. Select "Bond eno1 with" and "eno2" which creates "bond1"
  16. Accept the defaults and select "OK"
  17. Select "OK" to save changes or continue to the next section.

###Assign Logical Networks

  1. Connect and authenticate to oVirt
  2. Select "Data Centers"
  3. Select "Default" or your data center
  4. Select "Clusters"
  5. Select "Default" or your cluster
  6. Select "Hosts"
  7. Select "hosted_engine_1"
  8. Should default to "Hosts" tab otherwise select "Hosts"
  9. Select "Network Interfaces" tab
  10. Select "Setup Host Networks" button
  11. Drag infra101, sec121, intra131, dmz201, and dmz211 to bond1
  12. Select "OK" to save changes

Result with

ovirtnetworksinf

Repeat the above steps for "hosted_engine_2."
