Pinned topic CentOS 6, KVM, IOMMU and AMD-Vi

‏2013-10-02T23:05:04Z |


I try to install CentOS 6.4 on a x3455 with 2 x ADM 2218 dual core, later try to install KVM from official repositories, and the dmesg file show me that IOMMU are disable, but no BIOS IOMMU switch is present, a message in dmesg say AMD-Vi is disable by default, use amd_iommu=on, but KVM don't work yet.

Later i traied with iommu=calgary, iommu=soft, iommu=noagp, amd_iommu=isolated, etc. but with re same result, when create a virtual machine a recive a message like this:

kvm: Nested Virtualization enabled
kvm: 2087: cpu0 unhandled rdmsr: 0xc0010001
kvm: emulating exchange as write
kvm: 3380: cpu0 unhandled rdmsr: 0xc001100d
kvm: 3380: cpu0 unhandled rdmsr: 0xc0010112
kvm: 3380: cpu0 unhandled rdmsr: 0xc0010001

Really this system support KVM?, Where's  the IOMMU options in the BIOS?

Actually I have 10 System X3455 waiting for install and run KVM over CentOS.

Thanks in advance, some help are wellcome.
