Re "Communicated with developer and be told that it don't supported." Does "not supported" mean that qemu-kvm doesn't do multiboot, or that use of multiboot is not supported in RHEL-6? Hi Markus,
I attached the mail as the followingm,which was sent by developer.And a sample was also provided in it and hope it can help you.Thanks.

I wasn't aware of this. As far as I know we don't support multiboot,
so this help text should be modified in the man page.
FWIW the --help output lists only:
Linux/Multiboot boot specific:
-kernel bzImage use 'bzImage' as kernel image
-append cmdline use 'cmdline' as kernel command line
-initrd file use 'file' as initial ram disk
so we should be fine there.
Any issues please let me know.
Best regards,
Min
Upstream QEMU has quite a few features we don't support in RHEL. Some of them we make unavailable in RHEL. This should be done consistently in code and documentation. In particular, the unavailable feature should be removed from the RHEL man page as well. Others are still available, but their use is unsupported. We generally do *not* hide them. In particular, we generally don't remove them from man pages. As far as I can tell, the multiboot feature is of the second kind: it's available, but its use is unsupported. If that's correct, this bug should be CLOSED/NOTABUG. |
Description of problem: qemu-kvm don't support multiboot but help describes that it is supported.It should be removed from help document. Version-Release number of selected component (if applicable): qemu-kvm-0.12.1.2-2.209.el6.x86_64 How reproducible: always Steps to Reproduce: 1.install qemu-kvm 2.man qemu-kvm and find "Linux/Multiboot boot specific:" Linux/Multiboot boot specific: When using these options, you can use a given Linux or Multiboot kernel without installing it in the disk image. It can be useful for easier testing of various kernels. ... -initrd "file1 arg=foo,file2" This syntax is only available with multiboot. Use file1 and file2 as modules and pass arg=foo as parameter to the first module. Actual results:It shows that the multiboot is supported here.Communicated with developer and be told that it don't supported. Expected results: qemu-kvm don't support this option so please remove it from help. Additional info:
