Is there a limit on multiple virtual drives?
« on: August 24, 2014, 08:31:36 AM »
When I boot tc like this:

qemu -L . -hda tinycore.img  -hdb data1.img -hdc data2.img

(where tc was installed to  tinycore.img)

I only see sda1 and sdb1 in the mount tool  (and trying to mount sdc1 from the command line reports that it can't find the device)

Is there a limit of 2 virtual hard drives?

I noticed that qemu sees these as:
ide0-hd0
ide0-hd1
ide1-hd0

This belongs to Qemu forums / ml really. The third IDE is used for the cdrom drive.
The only barriers that can stop you are the ones you create yourself.

Attached images show that qemu sees the 3 devices, but tinycore only 2 of them...

I noticed there is a message about "unknown partition table" related to sdc, but it also says that it has been
attached as a SCSI disk  (in dmesg.png)

FALSE ALARM!  Sorry to have bothered you, but the error in dmesg got me thinking and I tried a different virtual drive for hdc/sdc1 and it worked!  I will do more testing myself next time before I ask for help.
