From: Andrew Jones Date: Tue, 22 Sep 2015 13:54:55 +0000 (+0200) Subject: Add QEMU/KVM detection for ACPI-boot ARM X-Git-Tag: v1.16~21 X-Git-Url: http://git.annexia.org/?a=commitdiff_plain;h=163024ab11d1ff722c40c517be2279469614bc37;p=virt-what.git Add QEMU/KVM detection for ACPI-boot ARM Detect QEMU/KVM on ARM guests that have been boot with ACPI, i.e. without device tree. When boot with ACPI SMBIOS is populated, so we can use dmidecode.
