Moving forward and for the purposes of Fedora 15 development, can we get both patched 2.7.37/38 kernels that support DomU and raw upstream kernels? Or does xen/next-2.6.27 not have the requisite features yet anyway? This kernel works as expected with one exception. The exception has been a nagging problem, but I have not reported it because 1) we are using a research OS in DomU and 2) we are not clear if the problem is in our code, Linux or Xen. But, here are the symptoms: Occasionally (this seems to correlate to network activity between Dom0 and DomU), the system becomes unresponsive. I am running the Michael Young kernel at runlevel 3 within Dom0 (very little memory used by applications). Our OS runs in DomU and is constrained to 128MB of memory. When the system is unresponsive, typing a character into a Dom0 console take 2-5 seconds to appear on the screen. Likewise, other activity is extremely slow. As I mentioned, we have not been able to isolate where the problem is. Running, for example, an OpenWrt Linux build in DomU does not have this problem. > For those of you that are trying 2.6.37, I have built a vanilla 2.6.37-rc4 > kernel (no additional xen patches) at > http://koji.fedoraproject.org/koji/taskinfo?taskID=2635700 This kernel is the first from the 37/38 series that I have tested since I tested the initial upstream Xen accept. This seems to work within my expectations with two exceptions: 1. There are some warning related to nouveaufb. When I have time I will investigate a bit more, but 2.6.32 never really worked right for me with the nouveau drivers either. 2. On the positive side, it seems that the console back-end driver works. When I booted a DomU OS I received console messages. This surprised me. Soon after, Xen was unable to set up the networking for DomU, which is what I expected. Dom0 continued to operate fine even though loading an OS in DomU failed. -- Mike :wq -- xen mailing list email@example.com https://admin.fedoraproject.org/mailman/listinfo/xen
