Hi all, I recently upgraded my Xen 3.2.1 to 3.3.1 on Centos 5.2. Everything seems to have gone pretty smoothly except I have a few issues. My system specs are: 4GB RAM Q6600 quad core Intel CPU P5E-VM DO Q35 Intel mobo (VT-d enabled) Skystar2 DVB PCI card passed through to HVM DomU HVM Windows XP SP3 DomU 1. When I restart my DomU, it shuts down and turns into Domain-Unnamed but doesn't restart. I did notice it restarts when using a stubdom however. I suspect it may have to do with the VT-d PCI passthrough device though. 2. I was able to configure my DomU HVM to use a stubdom, but my passthrough PCI device wil not show in the DomU. Does Xen support VT-d passthrough when using a stubdom? 3. With my 3.2.1 install, I couldn't use vcpu=2 for my HVM DomU, because RTSP streaming would fail. Someone mentioned to use timer_mode=1 but from what I read this is the default now in the newer releases. RTSP streaming now works with vcpu=2 however there is a slight stuttering with the audio that I cannot seem to get rid of. I'm having trouble figuring out how to set the CPUID to a dual core instead of a dual cpu, can someone send me an example of a dual-core cpuid config for my hvm config? I'm hoping the CPUID may solve this stuttering audio issue. 4. What are the latest GPLPV drivers to use with a non-stubdom DomU? Are the GPLPV drivers still required with stubdom? Thanks in advance. _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
