Frequently Asked Questions

• What are the VKernel default credentials?
  
  User Name: vkernel
  Password: vkernel
  Root password: password

• What username and password should I use to log in to UI? Is it system user?
  Username: vkernel
  Password: vkernel
  No, it's not a system user.

• I have a problem with updating my version, I get an unrouted address error.
  Please do the following:

  1. Log in as root (Username: root; Password: password)
  2. Run perl -pi -e 's/^export\sVK_UP_SERVER.+//g' /etc/profile.d/vkernel.sh
  3. Log out and login again
  4. Run updateit.sh from /usr/local/vkernel/scripts

• How can I set static IP?
  To set up static address you need:

  1. Login as root
  2. Run yast
  3. Follow to Network Devices -> Network Card
  4. Select Change...
  5. Select network and click Edit
  6. Select Static address setup and type the address
  7. Select Routing and enter Default Gateway IP. If you do not have gateway and the appliance has IP from the same subnet as ESX/VC, specify the same IP (as in point 6) as Default Gateway. Do not leave Default Gateway empty!

• I changed the appliance IP, making it static IP , but I can't connect using http.
  Please check if the appliance IP conflicts with an existing one (shutdown the appliance and try to ping). Also check default gateway. If IP and default gateway are right try to connect to http and look at the system log on /var/log/message to find an error message.

• How do I get my log files?
  To get the log files, please, do the following:

  1. Connect to VKernel appliance via FTP
     (see How to enable FTP on VKernel virtual machine)
     Login: vkernel,
     Password: vkernel
     (Use an FTP client instead of using of Internet Explorer)
  2. Open /usr/local/vkernel/log/ directory
  3. Download all the files from that directory to your hard drive.

• How do I enable FTP on VKernel virtual machine?
  To enable FTP follow the instructions below:

  1. Log in as root
  2. Run command: perl -pi -e 's/disable\s+=\s+yes/disable = no/i' /etc/xinetd.d/vsftpd
  3. Run command: /etc/init.d/xinetd restart

• What browser can I use for viewing?
  Internet Explorer 6, 7

• How can I make a chargeback report for a vm on a different host?
  It's easy. Simply create a business service and assign any vm residing on any host to it. Add that business service to a customer, right click and create a chargeback report.

  To improve performance you can make some changes through VMWare Infrastructure Client:

  1. Select all available processors (right click on vm and select Edit Settings, select CPU and select count of it. Note: vm should be shutdown before)
  2. You can select as faster storage as you have (It should be done during deploying).
  3. Increase amount of memory (right click on vm and select Edit Settings, select Memory and select amount of it. Note: vm should be shutdown before).
