I did a grep in oe-core and meta-openembedded, it seems that no ? In oe-core: $ grep 'COMPATIBLE_MACHINE.*qemux86' meta/recipes* -r linux-yocto_4.4.bb:COMPATIBLE_MACHINE = "qemuarm|qemuarm64|qemux86|qemuppc|qemumips|qemumips64|qemux86-64" linux-yocto-tiny_4.4.bb:COMPATIBLE_MACHINE = "(qemux86)" linux-yocto-dev.bb:COMPATIBLE_MACHINE = "(qemuarm|qemux86|qemuppc|qemumips|qemumips64|qemux86-64)" linux-yocto-tiny_4.1.bb:COMPATIBLE_MACHINE = "(qemux86)" linux-yocto-rt_4.1.bb:COMPATIBLE_MACHINE = "(qemux86|qemux86-64|qemuarm|qemuppc|qemumips)" linux-yocto-rt_4.4.bb:COMPATIBLE_MACHINE = "(qemux86|qemux86-64|qemuarm|qemuppc|qemumips)" linux-yocto_4.1.bb:COMPATIBLE_MACHINE = "qemuarm|qemuarm64|qemux86|qemuppc|qemumips|qemumips64|qemux86-64" In meta-openembedded: vboxguestdrivers_4.3.30.bb:COMPATIBLE_MACHINE = "(qemux86|qemux86-64)" We can see that the only one sets qemux86 but no set qemux86-64 is linux-yocto-tiny: COMPATIBLE_MACHINE = "(qemux86)" And it really doesn't work with qemux86-64. // Robert
