Hi Aihua Liang, Sorry for the delay. A few questions if you don't mind. (In reply to aihua liang from comment #0) > -netdev tap,id=hostnet10 \ How is tap networking configured in the host? Are you sure that the guest is able to access a network with a running PXE server? If you boot an operating system from the virtual disk, does it have access to the right network (i.e. is the issue limited only to seabios / pre-boot environment)? > Additional info: > seabios log &screen snapshot as attachment. I'd be interested in seeing iPXE screen shots. The attached seabios log looks fine to me. Thanks! Ladi No available resource now, will give info as soon as possible.

PXE Boot Screen
Misunderstanding of PXE Boot in RedHat Engineering Lab. From the captured pxe boot screen, we can see that: Install menu can't be entered automatically, you should enter "menu" in boot prompt, then you can select the os you want to install. If you do nothing, it will skip pxe boot and try to boot from other devices. Manually enter boot install menu, select an OS, then install it. The guest os was installed successfully and worked normally. So, close the bug as "NOTABUG". |
