[vfio-users] VM doesn't book with kernel 4.2.3-1-vfio

[Okky Hendriansyah]

Hi,

The GLib warning is because of the upgrade on GLib which makes existing QEMU throw this warning. I remove the warning by applying the patch from https://lists.gnu.org/archive/html/qemu-devel/2015-09/msg04438.html 

You might want to try linux-vfio-lts, the package maintainer of linux-vfio made an LTS version which is based on 4.1.10 kernel (https://aur.archlinux.org/packages/linux-vfio-lts/).

Thanks.

Since I´m unable to fix this issue and there doesn´t seem to be much information about it... is there an archive where I can get an older pkgbuild for a 4.1 vfio kernel?

Regards
Alex

OK I got rid of the GLib-Warning, but the KVM error is still there.

Are you using OVMF?
I don't know if this is the same because you also getting
"(process:3267): GLib-WARNING **: gmem.c:482: custom memory allocation
vtable not supported" but there is a known bug in ovmf, since kernel 4.2
because of changes in kvm, you wont be able to start properly VM with
more than one core,
