Re: [Qemu-discuss] Problem converting from vmdk to raw format
qemu-img used the "sparse file" feature of your file system to not actually allocate disk sectors for many of the all-zero blocks in the raw file. Your iso creation tool did not.

However df shows that the space used in the partition is only 8.x GB. And now I am converting the raw file to an iso file and the iso is really occupying space. So why the space occupied by the raw file seems to do not exists and the one from Iso does? And why the Iso is becaming so big? Thanks for the aid. 2016-02-01 2:40 GMT-02:00, Fam Zheng : On Mon, 02/01 01:53, Alexandre Schenberg wrote: Hello, I tried to convert a .vmdk file to a raw file with this command: "qemu-img convert -f vmdk /media/windows/WinXP-disk1.vmdk winxp.raw" The result was: "qemu-img: Could not open '/media/windows/WinXP-disk1.vmdk" I am sure that the vmdk file, WinXP-disk1.vmdk it is in the dir /media/windows So what I am doing wrongly? Which qemu-img version are you using? Or which commit in the case of git tree? Enjoy Jakob -- Jakob Bohm, CIO, Partner, WiseMo A/S. https://www.wisemo.com Transformervej 29, 2860 Søborg, Denmark.

[Qemu-discuss] QEMU GD5446 Problems with WfW 3.11 and Windows 95
Hello, I try actually to setup a Windows for Workgroups (WfW 3.11) in qemu. With -vga vmware and a patched svg256.drv i could use up to 1024x768 with 256 colours. Every time i try -vga cirrus and ANY! GD5446 driver disk i get a damaged screen or the message, that WfW 3.11 could not init the video card. A lot of searches later there is no solution for this. Does anyone succeeded to use WfW 3.11 on qemu with more than 256 colours? On Windows 95 the system says that there is no GD5446 in the PC (qemu). Does anyone succeed to run Win 95 in qemu with -vga cirrus at i.e. 1024x768 with 16Bit depth? Best regards qemu newbee Wolfgang Bavaria
