It seems the PCI memory stomp is still happening. > If you boot Xen with guest_loglvl=all and then run the guest the consoel (xl dmesg) should also have the output from QEMU - that will help in seeing how it constructs the E820 (which was the problem last time). Are you also able to get the serial log from the guest? (IF this is Linux?) I usually have this in my guest config: serial='pty' and when Linux boots up I add 'console=ttyS0,115200 loglevel=8 debug' which will output everything to the 'xl console <guest> | tee /tmp/log'. > I am using qemu-dm, as I did on Xen 4.2.x. > > So whatever fix for this went into 4.3.0 didn't fix it for me. > Passing less than 2GB of RAM to domU till works fine. > > I have attached: > > qemu-dm log for domU > xl dmesg > domid: 1 > Using file /dev/zvol/ssd/edi in read-write mode > Watching /local/domain/0/device-model/1/logdirty/cmd > Watching /local/domain/0/device-model/1/command > Watching /local/domain/1/cpu > char device redirected to /dev/pts/3 > qemu_map_cache_init nr_buckets = 10000 size 4194304 > shared page at pfn feffd > buffered io page at pfn feffb > Guest uuid = a57e6840-e9f5-4a14-a822-b2cc662c177f > populating video RAM at ff000000 > mapping video RAM from ff000000 > Register xen platform. > Done register platform. > platform_fixed_ioport: changed ro/rw state of ROM memory area. now is rw > state. > xs_read(/local/domain/0/device-model/1/xen_extended_power_mgmt): read error > xs_read(): vncpasswd get error. > /vm/a57e6840-e9f5-4a14-a822-b2cc662c177f/vncpasswd. > Log-dirty: no command yet. > I/O request not ready: 0, ptr: 0, port: 0, data: 0, count: 0, size: 0 > I/O request not ready: 0, ptr: 0, port: 0, data: 0, count: 0, size: 0 > vcpu-set: watch node error. > [xenstore_process_vcpu_set_event]: /local/domain/1/cpu has no CPU!
