It could be a KVM bug too. The following features are being enabled: #define VMX_SECONDARY_EXEC_XSAVES 0x00100000 #define VMX_SECONDARY_EXEC_SHADOW_VMCS 0x00004000 #define VMX_SECONDARY_EXEC_ENABLE_INVPCID 0x00001000 #define VMX_SECONDARY_EXEC_RDRAND_EXITING 0x00000800 #define VMX_SECONDARY_EXEC_ENABLE_VPID 0x00000020 #define VMX_SECONDARY_EXEC_ENABLE_EPT 0x00000002 #define VMX_SECONDARY_EXEC_DESC 0x00000004 #define VMX_SECONDARY_EXEC_RDTSCP 0x00000008 Can you try: 1) running "vmxcap" on the Azure VM 2) adding "-vmx-xsaves,-vmx-shadow-vmcs" to the "-cpu" option and, if it works, add only one of the two. 3) if it doesn't work, adding "-vmx" to the "-cpu" option. Either way, run "x86info -a" in the resulting VM. Thanks, Paolo
