Oracle VM Set CPU Pinning/Affinity – Part 13


Step 1: Login to Oracle VM server as root

[root@mgmtsrv ~]# ssh ovm.lab.local
root@ovm.lab.local's password:
Last login: Sun Dec 17 05:34:13 2017 from 10.10.10.1
[root@ovm ~]#

Step 2: Enable TCPS [Secure way to connect and perform the tasks]

[root@ovm ~]# cd /u01/app/oracle/ovm-manager-3/bin/
[root@ovm bin]# ./secureOvmmTcpGenKeyStore.sh
Generate OVMM TCP over SSL key store by following steps:
Enter keystore password: ## Enter the password ##
Re-enter new password: ## Re-enter the password ##
What is your first and last name?
[Unknown]: Ora Admin
What is the name of your organizational unit?
[Unknown]: LAB
What is the name of your organization?
[Unknown]: TEST
What is the name of your City or Locality?
[Unknown]: Chennai
What is the name of your State or Province?
[Unknown]: Tamil Nadu
What is the two-letter country code for this unit?
[Unknown]: IN
Is CN=Ora Admin, OU=LAB, O=TEST, L=Chennai, ST=Tamil Nadu, C=IN correct?
[no]: yes


Enter key password for
(RETURN if same as keystore password): ## Enter above given password ##
Re-enter new password: ## Re-enter above given password ##

[root@ovm bin]# ./secureOvmmTcp.sh
Enabling OVMM TCP over SSL service

Please enter the Oracle VM manager user name: admin

Please enter the Oracle VM manager user password: ## Enter Oracle VM Manager admin password ##

Please enter the password for TCPS key store : ## Enter above created key store password ##

The job of enabling OVMM TCPS service is committed, please restart OVMM to take effect.

Restart the OVMM daemon

[root@ovm bin]# /etc/init.d/ovmm restart
Stopping Oracle VM Manager [ OK ]
Starting Oracle VM Manager [ OK ]

Below netstat output show that TCPS port is listening in Oracle VM Manager.

[root@ovm ~]# netstat -antulp | grep 54322
tcp 0 0 :::54322 :::* LISTEN 9042/java

Step 3: Install the Oralce VM Utils

[root@ovm ~]# mkdir OVMM

Download the below zip file from Oracle Support site.

[root@ovm ~]# unzip -d OVMM p13602094_30_Linux-x86-64.zip

Step 4: Verify the Oracle VM Server CPU topology and cpu list

Below command explains that Oracle VM Server has 2 Processors and 2 Cores per Processor, which means total 4 vcpu’s.

[root@ovs01 ~]# xenpm get-cpu-topology
CPU core socket node
CPU0 0 0 0
CPU1 1 0 0
CPU2 0 1 0
CPU3 1 1 0

Next I want to check which VM’s are using which CPUs. I have only one VM (0004fb0000060000524f9d3e43fd71f3) names as FirstVM which uses 2 vcpu threads. See CPU column (2,3).

[root@ovs01 ~]# xm vcpu-list
Name ID VCPU CPU State Time(s) CPU Affinity
0004fb0000060000524f9d3e43fd71f3 2 0 2 -b- 390.9 any cpu
0004fb0000060000524f9d3e43fd71f3 2 1 3 -b- 29.2 any cpu
Domain-0 0 0 1 -b- 237.7 any cpu
Domain-0 0 1 0 r-- 278.1 any cpu
Domain-0 0 2 3 -b- 152.5 any cpu
Domain-0 0 3 2 -b- 241.0 any cpu

Step 5: Check whether CPU’s are pinned for the new VM.

[root@ovm ovm_utils]# ./ovm_vmcontrol -u admin -p ************ -h ovm.lab.local -v FirstVM -c vcpuget
Oracle VM VM Control utility 2.0.1.
Connecting with a secure connection.
Connected.
Command : vcpuget
No vcpu's pinned for this Virtual Machine.

Above output shows that CPU’s are not pinned for the VM.

Step 6: Pin both CPUs to core 0 and 1.

It is recommend to reboot the VMs after CPU pinning to get the changes effective.

[root@ovm ovm_utils]# ./ovm_vmcontrol -u admin -p ************ -h ovm.lab.local -v FirstVM -c vcpuset -s 0,1
Oracle VM VM Control utility 2.0.1.
Connecting with a secure connection.
Connected.
Command : vcpuset
Pinning virtual CPUs
Pinning of virtual CPUs to physical threads '0,1' 'FirstVM' completed.

[root@ovm ovm_utils]# ./ovm_vmcontrol -u admin -p ************ -h ovm.lab.local -v FirstVM -c vcpuget
Oracle VM VM Control utility 2.0.1.
Connecting with a secure connection.
Connected.
Command : vcpuget
Current pinning of virtual CPUs to physical threads : 0,1

Step 7: Confirm the CPU pinning by access and run the below command in the Oracle VM Server.

[root@ovs01 ~]# xm vcpu-list
Name ID VCPU CPU State Time(s) CPU Affinity
0004fb0000060000524f9d3e43fd71f3 2 0 0 -b- 401.6 0-1
0004fb0000060000524f9d3e43fd71f3 2 1 1 -b- 29.4 0-1
Domain-0 0 0 3 -b- 240.0 any cpu
Domain-0 0 1 3 r-- 282.2 any cpu
Domain-0 0 2 2 -b- 154.2 any cpu
Domain-0 0 3 0 -b- 244.2 any cpu

Step 8: Alternate method to set CPUs from Oracle VM server

[root@ovs01 ~]# xm vcpu-pin 2 all 2-3


[root@ovs01 ~]# xm vcpu-list
Name ID VCPU CPU State Time(s) CPU Affinity
0004fb0000060000524f9d3e43fd71f3 2 0 3 -b- 409.8 2-3
0004fb0000060000524f9d3e43fd71f3 2 1 3 -b- 29.5 2-3
Domain-0 0 0 0 -b- 242.3 any cpu
Domain-0 0 1 2 -b- 285.7 any cpu
Domain-0 0 2 1 r-- 155.6 any cpu
Domain-0 0 3 0 -b- 247.2 any cpu

How to Restore Oracle VM Manager without Database Backup or Admin Password – Part 12


In our previous post (Part 8) we have discussed how to recover the Oracle VM Manager using MySQL database. For that we need MySQL backup and admin & weblogic user password. But sometimes we might have chance to forget the admin or weblogic user password and also no backup of Oracle VM Manager MySQL database. In that case, we need to follow the below steps to recover the Oracle VM Manager.

Before starting our VM manager installation we need the existing Manager UUID value. The Oracle VM Manager UUID is located in Oracle VM Manager server (/u01/app/oracle/ovm-manager-3/.config) file and as well as in each server pool’ .ovsrepo file (OVS_REPO_MGR_UUID=UUID) located in the pool file system.

[root@mgmtsrv ~]# cat /repo2/.ovsrepo
OVS_REPO_UUID=0004fb000003000082b0d717e2f9871d
OVS_REPO_VERSION=3.0
OVS_REPO_MGR_UUID=0004fb00000100009157557324ed168d
OVS_REPO_ALIAS=OraRepo

Step 1: Move the OVS agent db directory

This step is not required, however we need to perform if we get any ownership error or warning during discovering the Oracle Virtual Server.

[root@ovs01 ~]# /etc/init.d/ovs-agent stop
Stopping Oracle VM Agent: [ OK ]

[root@ovs01 ~]# mv /etc/ovs-agent/db /etc/ovs-agent/db_bak20171223

[root@ovs01 ~]# /etc/init.d/ovs-agent start
Starting Oracle VM Agent: [ OK ]

Step 2: Login to Oracle VM Manager as admin

[root@mgmtsrv ~]# ssh -l admin ovm.lab.local -p 10000
admin@ovm.lab.local's password:
OVM>

Step 3: Discover one Oracle VM Server from each server pool

OVM> discoverServer ipaddress=ovs01.lab.local password=********** takeOwnership=Yes
Command: discoverServer ipaddress=ovs01.lab.local password=**** takeOwnership=Yes
Status: Success
Time: 2017-12-23 03:47:27,748 EST
JobId: 1514018774243

Step 4: Discover the storage that contains the server pool file system. Present it to the newly discovered Oracle VM Server. Refresh the storage.

OVM> create FileServer plugin="Oracle Generic Network File System" accessHost=mgmtsrv.lab.local adminServers="ovs01.lab.local" name=MYSANRec
Command: create FileServer plugin="Oracle Generic Network File System" accessHost=mgmtsrv.lab.local adminServers="ovs01.lab.local" name=MYSANRec
Status: Success
Time: 2017-12-23 03:50:08,007 EST
JobId: 1514019007499

Command: addAdminServer FileServer name=MYSANRec server=ovs01.lab.local
Status: Success
Time: 2017-12-23 03:50:33,884 EST
JobId: 1514019033629

OVM> addRefreshServer FileServer name=MYSANRec server=ovs01.lab.local
Command: addRefreshServer FileServer name=MYSANRec server=ovs01.lab.local
Status: Success
Time: 2017-12-23 03:50:58,303 EST

Status: Success
Time: 2017-12-23 03:51:24,544 EST
JobId: 1514019082774

Step 5: Refresh the file systems or physical disks that contain the server pool file system

OVM> list FileSystem
Command: list FileSystem
Status: Success
Time: 2017-12-23 03:51:33,554 EST
Data:
id:9f4e1109-2c5b-4bae-834b-0ccc203e5ab6 name:nfs on mgmtsrv.lab.local:/repo2
id:f3834a16-6fcb-4f82-9a2a-b3d3ed936ae3 name:nfs on mgmtsrv.lab.local:/repo1

OVM> refresh FileSystem name="nfs on mgmtsrv.lab.local://repo1"
Command: refresh FileSystem name="nfs on mgmtsrv.lab.local://repo1"
Status: Success
Time: 2017-12-23 03:52:49,786 EST
JobId: 1514019168044

Step 6: Refresh the file systems or physical disks that contain the repositories used by server pool

OVM> refresh FileSystem name="nfs on mgmtsrv.lab.local://repo2"
Command: refresh FileSystem name="nfs on mgmtsrv.lab.local://repo2"
Status: Success
Time: 2017-12-23 03:52:54,608 EST
JobId: 1514019173387

Step 7: Present the repositories to the Oracle VM Server

OVM> add Server name=ovs01.lab.local to ServerPool name=Pool_01
Command: add Server name=ovs01.lab.local to ServerPool name=Pool_01
Status: Success
Time: 2017-12-23 03:57:10,904 EST
JobId: 1514019424928

OVM> list ServerPool
Command: list ServerPool
Status: Success
Time: 2017-12-23 03:57:18,884 EST
Data:
id:0004fb00000200002d1d67487c79ed89 name:Pool_01

OVM> add ServerPool name=Pool_01 to Repository name=OraRepo
Command: add ServerPool name=Pool_01 to Repository name=OraRepo
Status: Success
Time: 2017-12-23 03:59:06,197 EST
JobId: 1514019545102

Step 8: Refresh the repositories

OVM> refresh Repository name=OraRepo
Command: refresh Repository name=OraRepo
Status: Success
Time: 2017-12-23 03:59:20,625 EST
JobId: 1514019559448

Step 9: Check the VM list

OVM> list vm
Command: list vm
Status: Success
Time: 2017-12-23 04:04:50,724 EST
Data:
id:0004fb0000060000524f9d3e43fd71f3 name:FirstVM

OVM> start vm name=FirstVM
Command: start vm name=FirstVM
Status: Failure
Time: 2017-12-23 04:05:36,388 EST
JobId: 1514019936121
Error Msg: Job failed on Core: OVMRU_005053E: Virtual Machine: FirstVM, is not associated with any server pool [Sat Dec 23 04:05:36 EST 2017]

In above command, I’m trying to start the Virtual Machine but it failed because the VM “FirstVM” is not associated with any server pool. So we need to move this VM to corresponding Server Pool.

OVM> migrate Vm name=FirstVM destServerPool=Pool_01
Command: migrate Vm name=FirstVM destServerPool=Pool_01
Status: Success
Time: 2017-12-23 04:13:31,390 EST
JobId: 1514020411131

OVM> start vm name=FirstVM
Command: start vm name=FirstVM
Status: Success
Time: 2017-12-23 04:13:45,270 EST
JobId: 1514020416903
