I am a hobbyist, running a desktop, latest version, open-suse (15.0) system. I have recently changed to an AMD processor having used intel for a long time. I generally format and do a clean install on /, but have a /home partition which has been around for many years and may contain entries related to the intel processor rather than the amd one. I am trying to install and run virtual box. On starting a virtual machine I get a message: AMD-V is disabled in the BIOS (or by the host OS) (VERR_SVM_DISABLED). My BIOS says that "Secure Virtual Machine" is enabled. cat cpuinfo |grep svm shows that svm is on each core. dmidecode does NOT list the svm flag Further system info: Base Board Information Manufacturer: Micro-Star International Co., Ltd. Product Name: B350M PRO-VDH (MS-7A38) Version: 2.0 Processor Information Socket Designation: AM4 Type: Central Processor Family: Zen Manufacturer: Advanced Micro Devices, Inc. Signature: Family 23, Model 1, Stepping 1 Thinking there may be detritus in my /home partition, I have created a new user, but experienced the same problem when starting the virtual machine. Any help on 'how to make virtual box work' would be appreciated, also any info on why cpuinfo says svm is available, but dmidecode does not? I am on and off line at the moment, so may take time to respond. Thank you in advance! H
