Hi, after adding the 'device_model_stubdomain_override = 1' to an otherwise fine configuration the domain crashes on start. Xen is v4.6.1 compiled from source on Debian Jessie 64bits this way: - ./configure --enable-stubdom --enable-githttp - make dist-xen - make dist-tools - make dist-stubdom - make install-xen - make install-tools - make install-stubdom As pointed out before the same configuration file without the ' device_model_stubdomain_override' works flawlessly. This is the 'xl list' command output while the domain is starting: Name ID Mem VCPUs State Time(s) Domain-0 0 1022 2 r----- 318.3 win7-sp1-x64-2 20 2048 1 r----- 5.5 win7-sp1-x64-2-dm 21 44 1 r----- 6.0 As you can see both domains are started (the stub and the original domain) Find attached the domain configuration file, 'xl info' output, 'xl create' output and the /var/log/xen/console/hypervisor.log file, notice the grant table error on console-hypervisor.log I'd very grateful for any help finding the cause of this problem. Best regards, Fanny
