I have one xen machine where dom0 libata and pcibacked domU eth0 share a physical IRQ. I thought that the disk was bad (cause the system was crashing and giveing me disk errors) and replaced it with an IDE disk connected to a pcibacked SATA-IDE combo card. Problem seems to have gone away. The machine runs stably and hasn't crashed yet. Now I have another machine where I pciback usb. The usb port in domU shares a physical irq with the dom0 libata. The machine crashes every few hours with disk errors. In the domU, I see usb related errors as well (usblp removed, etc.). Is there anyway to prevent the irq sharing? I think this is the cause of the crash. Thanks Chris _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
