Hi, I am trying to set up a customized image with xen hypervisor using the ubuntu-vm-builder tool. I follow the instructions in this page http://marss86.org/~marss86/index.php/Custom_Disk_Images and create a precise 12.04 ubuntu image with default disk size 4GB. This image can be correctly loaded and executed within the marssx86 in emulation mode. However, once I start the simulation mode using these commands
simconfig -machine xeon_single_core simconfig -run -stopinsns 10m -stats output.log after certain numbers of instructions, the simulation breaks with assertion failures. I observed two types of assertions: Assertion `ctx.page_fault_addr != 0' failed Assertion `physreg->data' failed I searched in the mailing list, it seems that the problem is caused by the corrupted images. I create several images with 12.04 and 11.10. They all have the same problem. I am not sure where is the problem. One thing I would like to mention is even if I specify the rootsize in the config file of ubuntu-vm-builder to other sizes such as 60gb/40gb, but the created image is always 4gb. I am not sure if this is related or not. I also tried the raw format image that created by virtualbox, the problem is same. The emulation part is OK even if an application is running in domu, but the simulation always breaks. Any suggestions would be appreciated. Thanks
