10 thoughts on - Running I386 Guests Under CentOS7 Amd64 Kvm Host

• Dear Martinez, You should be able to search the ubuntu guest under virtManager from CentOS
  desktop environment (Gnome for example). For New VM machine creation with Ubuntu guest, you just select OS type
  “Linux”, Version ” ubuntu12 ” subject to available. Hope that helps!

• Thanks XLord, but using virtual manager, there is not an option to select “i386” or “amd64” guest …

• In Step 5 of Create a New Virtual Machine, click on “Advanced options” and you will find the architecture selection options “x86_64” and “i686”.

• Thanks Bob, but there is not “Advanced options”. I can use “Customize configuration before install”, but if I use this option, architecture is fixed and it can not be changed …

  I am using virt-manager 1.2.1-8.el7.

  Mnay thanks.

• Looks like it’s absent in that version. It’s there in virt-manager-0.9.0-31.el6.x86_64.

• Dear Martinez, Hum…do you choose paravirtualized or fully virtualized?

• But 0.9.0 is older than 1.2.1 …

• Sorry? There is not such option when you use KVM as a hypervisor …

• I thought that was obvious. I was just explaining where I was seeing that option.

  The i386 guest should run fine in a normal x86_64 setup, right? You can install 32bit Ubuntu on a physical x86_64 machine, right?
