NAME

6       qemu-sanity-check - run a simple sanity check on qemu and the Linux
7       kernel

SUMMARY

10       qemu-sanity-check [options]
11

DESCRIPTION

13       qemu-sanity-check is a short shell script that test-boots a Linux
14       kernel under qemu, making sure it boots up to userspace.  The idea is
15       to test the Linux kernel and/or qemu to make sure they are working.
16
17       You can use the command on its own:
18
19        qemu-sanity-check
20
21       In this case, the script will look for a suitable qemu binary on the
22       $PATH and the latest Linux kernel in "/boot" and try to boot that
23       kernel on that qemu.
24
25       You can also specify a qemu binary or a Linux kernel (either or both
26       options can be omitted):
27
28        qemu-sanity-check --qemu=/path/to/qemu --kernel=/path/to/vmlinuz
29
30   KVM
31       KVM ("kvm" or "qemu-kvm") can be used in place of qemu.
32
33   KERNEL DRIVERS
34       No kernel modules or special drivers are required except as noted
35       below.  The test uses an initramfs containing a static binary, so the
36       kernel is not required to locate block devices, use virtio, mount
37       filesystems, etc.
38
39       The kernel must support only the following, compiled in (not as
40       modules):
41
42       ·   A serial port (usually: "CONFIG_SERIAL_8250=y")
43
44       ·   Initrd/initramfs ("CONFIG_BLK_DEV_INITRD=y")
45

OPTIONS

47       --help
48           Display short help message and exit.
49
50       --accel=kvm
51       --accel=tcg
52       --accel=kvm:tcg
53           This sets the "-machine accel=..." parameter which is passed to
54           qemu.
55
56           If not set, then "kvm:tcg" is the default, which means to try to
57           use KVM (hardware-assisted virtualization), and fall back to
58           software emulation if KVM is not possible.
59
60           Other typical values of this parameter are: "tcg", which means to
61           force software emulation.  "kvm", which means to force KVM and fail
62           if KVM is unavailable.
63
64       -i INITRD
65       --initrd=INITRD
66           Use the initramfs image named "INITRD" instead of the default.
67
68       -k VMLINUZ
69       --kernel=VMLINUZ
70           Use the kernel image "VMLINUZ" instead of searching for the latest
71           kernel installed in "/boot".
72
73       -q QEMU
74       --qemu=QEMU
75           Use the qemu (or KVM) binary "QEMU" instead of searching $PATH for
76           a suitable binary.
77
78       -t TIMEOUT
79       --timeout=TIMEOUT
80           Specify a timeout instead of the default which is "10m" (10
81           minutes).
82
83           The syntax for the "TIMEOUT" is described in full in the man page
84           for timeout(1).
85
86       -V
87       --version
88           Display version and exit.
89

EXIT STATUS

91       The exit status is 0 if the Linux kernel booted as far as userspace
92       under qemu; or if the --help or --version options were used.
93
94       The exit status is 1 if the kernel boot failed under qemu.
95
96       The exit status is 2 if the script itself failed (eg. incorrect command
97       line options were used, a suitable kernel could not be found).
98

FILES

100       /usr/lib64/qemu-sanity-check/initrd
101           The default location for the small initramfs image that is used to
102           test that userspace has been reached.
