6.4.11 Cannot Create a Virtual Machine from Installation Media

When creating a virtual machine, the following message may be displayed:

Error: There is no server supporting hardware virtualization in the selected server pool.

To resolve this issue, make sure the Oracle VM Server supports hardware virtualization. Follow these steps to check:

  1. Run the following command to check if hardware virtualization is supported by the CPU:

    # cat /proc/cpuinfo |grep -E 'vmx|smx'

    If any information that contains vmx or smx is displayed, it means that the CPU supports hardware virtualization. Here is an example of the returned message:

    flags : fpu tsc msr pae mce cx8 apic mtrr mca cmov pat pse36 clflush dts acpi mmx fxsr 
    sse sse2 ss ht tm pbe nx lm constant_tsc pni monitor ds_cpl vmx est tm2 cx16 xtpr lahf_lm

    The /proc/cpuinfo command only shows virtualization capabilities starting with Linux 2.6.15 (Intel®) and Linux 2.6.16 (AMD). Use the uname -r command to query your kernel version.

  2. Make sure you have enabled hardware virtualization in the BIOS.

  3. Run the following command to check if the operating system supports hardware virtualization:

    # xm info |grep hvm

    The following is an example of the returned message:

    xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x 

If the CPU does not support hardware virtualization, use the paravirtualized method to create the virtual machine. See Create Virtual Machine in the Oracle VM Manager User's Guide for information on creating a paravirtualized virtual machine.
