With my older machine locking up once too often at in-opportune times,
I've switched over to a newer machine, which I've tried to set up
identically. QEMU is not laumching. It worked on the older system.
The error message is...
[x8940][waltdnes][~] /home/misc/qemu/arca/boot
Could not access KVM kernel module: No such file or directory
qemu-system-x86_64: failed to initialize kvm: No such file or directory
My user is a member of the kvm group, and I get the same error trying
to launch as root
My system...
* 12-core Intel Skylake with 16 gigs of ram, 64-bit gentoo
* Yes, KVM support is installed in the kernel...
[x8940][waltdnes][~] zgrep KVM_INTEL /proc/config.gz
CONFIG_KVM_INTEL=y
* make.conf contains
QEMU_SOFTMMU_TARGETS="i386 x86_64"
QEMU_USER_TARGETS="i386 x86_64"
* including flags in package.use, I get
[x8940][waltdnes][/etc/portage/package.use] emerge -pv qemu
These are the packages that would be merged, in order:
Calculating dependencies... done!
