Unable to run linux kernel image on qemu -

-

i have compiled linux kernel (stable) tree , got initrd , bzimage. try running on qemu emulator having trouble specifying root file system partition. (i know partition thats loaded run initrd from).

my system ubuntu 12.04 installed via wubi on windows.

the command have been using 

qemu-system-x86_64 -kernel bzimage  -initrd initrd.img-3.11 -append "root=/no-clue-what-to-put"

i know root argument specifies root partition is. image running on qemu appreciated.

do have disk image , root filesystem give qemu , kernel?

you need more linux kernel boot linux system. qemu, need root filesystem contained within virtual disk image well. contain programs kernel "hands control" when it's done booting, 'init' or 'systemd'.

so have generate qemu-disk image contains root filesystem. if created such root filesystem on first partition of virtual disk, can specify virtual disk parameter qemu "-hda /path/to/qemu/disk/image", , can tell kernel use first partition of virtual disk "-append "root=/dev/sda1" (it /dev/vda1 or /dev/hda1 depending on kind of disk image created).

so final command like:

qemu-system-x86_64 -kernel bzimage -initrd initrd.img-3.11 -hda /path/to/your/qemu/disk/image -append "root=/dev/sda1"

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
