virt-what version : 1.18.4.el7 (CentOS) Although this is a somewhat older version of virt-what I did take a look at the latest 1.21 and the issue persists I have noticed a bug with virt-what mis-reporting in AWS. The upshot is that it reports as
xen xen-hvm only. I took a look at the code and the dmi responses on the systems that were “failing” and found the following. # Check for AWS if echo "$dmi" | grep -q 'Version: [0-9]\.[0-9]\.amazon'; then echo aws fi AWS has since updated its versions : BIOS Information Vendor: Xen Version: 4.11.amazon … System Information Manufacturer: Xen Product Name: HVM domU Version: 4.11.amazon Obviously the above pattern match will not succeed. I have updated my virt-what to
# Check for AWS if echo "$dmi" | grep -q 'Version: [0-9]*\.[0-9]*\.amazon'; then echo aws fi Which restores the output I am expecting xen xen-hvm aws but wanted to report this back to the project to get a proper fix for all. I’m aware that the * may add a bit too much scope but [0-9][0-9] may also be too restrictive for the future. Regards, Stuart Cooper |
