aarch64 ? x86_64 ? or both ? Why should I go to an unknown (to me) URL to look at an image? What is so difficult about following the procedure that has been documented? |
|
|
I think it is x86_64. But you might as well do the aarch64 if that is not a problem. No need to look at the image. It is a snapshot of "make config" highlighting the 'XEN_PVH guest support' line. |
|
|
The configuration option has been queued and will be enabled once the relevant section of both configuration files is reached. |

@prymar56 filed a request for Xen here: https://elrepo.org/bugs/view.php?id=1194#c8645 |

The two configuration files are still very much "work in progress".

I have a rebuild of this will full dom0/domU xen support installed and working, I took a look at the fc36 xen config for a similar kernel: CONFIG_XEN_FBDEV_FRONTEND=y CONFIG_XEN_SCSI_FRONTEND=m CONFIG_XEN_WDT=m CONFIG_DRM_XEN_FRONTEND=m CONFIG_USB_XEN_HCD=y CONFIG_XEN_BALLOON=y CONFIG_XEN_BALLOON_MEMORY_HOTPLUG=y CONFIG_XEN_BACKEND=y CONFIG_XEN_GNTDEV=m CONFIG_XEN_GRANT_DEV_ALLOC=m # CONFIG_XEN_GRANT_DMA_ALLOC is not set CONFIG_XEN_GRANT_DMA_OPS=y CONFIG_XEN_VIRTIO_FORCE_GRANT=y CONFIG_XEN_VIRTIO=y CONFIG_XEN_UNPOPULATED_ALLOC=y These are the corrected settings for dom0 and especially domU in dom0 guest support. IOW for dom0 to create domU guests, these are needed. The above settings were missing or wrong in the elrepo config above for x86_64. |

@prymar56 Thank you. I've opened a separate issue (below) so we can track the request: https://elrepo.org/bugs/view.php?id=1272 We will feed back there once this has been added to the config. |

Resolved with the release of kernel-ml-6.0.0-1.el9.elrepo. |
