You need to change QEMU_RUN_OPT in build/x86_64/etc/build.conf to image/disk instead of image/iso... like Yvan Loskutov said in a previous email. [worked, but then would break the QEMU run I guess... maybe we could boot qemu from a virtual USB stick and have it work in "all" the cases?] > > Cédric I have tried to dd the demo.iso file on my stick USB. At first, I thought I was proving me right because it did not boot. But then I realized I was trying to boot only in UEFI USB mode. So I tried LEGACY USB, and found that it does indeed boot that way. _______________________________________________ users mailing list -- users@lists.genode.org To unsubscribe send an email to users-le...@lists.genode.org Archived at https://lists.genode.org/mailman3/hyperkitty/list/users@lists.genode.org/message/TE7CJ44IDZUJNGGGYW77C64ZBFJA26DF/
