Since this was last looked at over 10 years ago, it's extremely likely your issue is completely unrelated to the originally reported one. Here are a couple pages on how to write effective bug reports, that I'd encourage reading to ensure your report is actionable and can (hopefully) get resolved expediently: * https://help.ubuntu.com/community/ReportingBugs * https://ubuntu.com/server/docs/reporting-bugs A few other tips specific to qemu (per the upstream bug tracker): * Include the QEMU release version or the git commit hash into the descri= ption, so that it is later still clear in which version you have found the = bug. Reports against the latest release or even the latest development tree= are usually acted upon faster. * Include the full command line used to launch the QEMU guest. * Reproduce the problem directly with a QEMU command-line. Avoid frontend= s and management stacks, to ensure that the bug is in QEMU itself and not i= n a frontend. * Include information about the host and guest (operating system, version= , 32/64-bit). -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/304636 Title: -hda FAT:. limited to 504MBytes Status in QEMU: Confirmed Status in qemu package in Ubuntu: Won't Fix Bug description: Binary package hint: qemu The size of the virtual FAT file system (for sharing a particular directo= ry with Guest OS) is hard-coded to be limited to 504MBytes, in block-vvfat.c -- /* 504MB disk*/ bs->cyls=3D1024; bs->heads=3D16; bs->secs=3D63; -- If the directory contents exceeds this is stops with an assert -- qemu: block-vvfat.c:97: array_get: Assertion `index < array->next' failed.
