3.7 Troubleshooting
In some circumstances, problems may occur during the installation of the VM Guest.
This section describes some known problems and their solutions.
During boot, the system hangs
The software I/O translation buffer allocates a large chunk of low memory early
in the bootstrap process. If the requests for memory exceed the size of the buffer
it usually results in a hung boot process. To check if this is the case, switch to
console 10 and check the output there for a message similar to
kernel: PCI-DMA: Out of SW-IOMMU space for 32768 bytes at device
000:01:02.0
In this case you need to increase the size of the swiotlb. Enter "swiotlb=128"
on the Domain0 command line. Note that the number can be adjusted up or down
to find the optimal size for the machine.
