If installed app-emulation/xen-tools with USE=system-qemu that installation misses /usr/libexec/xen/bin/qemu-system-i386 However this would be needed to provide backward compatibility e.g. for app-emulation/libvirt see also fedora bugs at https://bugzilla.redhat.com/show_bug.cgi?id=1299745 https://bugzilla.redhat.com/show_bug.cgi?id=1334554 A proposed workaround would be to generate a symlink to /usr/bin/qemu-system-x86_64 or whatever corresponds to your platform.
would this following patch fix your problem? btw, /usr/libexec/xen/bin/qemu-system-i386 is part of app-emulation/xen-tools if USE=qemu is enabled # qfile /usr/libexec/xen/bin/qemu-system-i386 app-emulation/xen-tools (/usr/libexec/xen/bin/qemu-system-i386) --- xen-tools-4.7.0-r2.ebuild 2016-11-04 20:20:55.417173061 +0800 +++ xen-tools-4.7.0-r3.ebuild 2016-11-10 09:25:52.713708370 +0800 @@ -345,7 +345,6 @@ --disable-xen \ --enable-tools \ --enable-docs \ - $(use_with system-qemu) \ $(use_enable pam) \ $(use_enable api xenapi) \ $(use_enable ovmf) \ @@ -354,7 +353,7 @@ " use system-seabios && myconf+=" --with-system-seabios=/usr/share/seabios/bios.bin" - use qemu || myconf+=" --with-system-qemu" + use system-qemu && myconf+=" --with-system-qemu=/usr/bin/qemu-system-x86_64" use amd64 && myconf+=" $(use_enable qemu-traditional)" econf ${myconf} }
Created attachment 453934 [details, diff] qemu-path.patch Some source browsing in app-emulation/libvirt brought me a semi hard-coded path, which needs to be replaced to work properly for xen[system-qemu] NB: Of course integrated qemu could be used, however this won't offer spice and other nice qemu drivers and features. The proposed patch addresses the problem at its root. I didn't manage to autodetect qemu-system-ARCH - which would be more generic than just "x86_64"
hi thomas, did you try the latest versions? current all versions in tree should already fixed this problem, and no need to patch app-emulation/libvirt I'm closing this bug as fixed, but in case if you still have problem, please re-open it
