Upgrade to 7.6 but amd ryzan cpu always not support.
I has upgrade xcp-ng to 7.6 rc version.The IOMMU has support it.But the amd ryzan cpu always not support it.It's may need kernel 4.11 version.Could upgrade new kernel in the feature?
@akong77 We have an alternate kernel 4.9 available https://github.com/xcp-ng/xcp/wiki/Alternate-kernel
However, is there a specific kernel config that you want from 4.11?
# grep IOMMU /boot/config-4.4.0+10 | grep -v \# CONFIG_GART_IOMMU=y CONFIG_CALGARY_IOMMU=y CONFIG_CALGARY_IOMMU_ENABLED_BY_DEFAULT=y CONFIG_IOMMU_HELPER=y CONFIG_IOMMU_API=y CONFIG_IOMMU_SUPPORT=y CONFIG_IOMMU_IOVA=y CONFIG_AMD_IOMMU=y CONFIG_AMD_IOMMU_V2=m CONFIG_INTEL_IOMMU=y CONFIG_INTEL_IOMMU_FLOPPY_WA=y
# grep IOMMU /boot/config-4.9.0+0 | grep -v \# CONFIG_GART_IOMMU=y CONFIG_CALGARY_IOMMU=y CONFIG_CALGARY_IOMMU_ENABLED_BY_DEFAULT=y CONFIG_IOMMU_HELPER=y CONFIG_IOMMU_API=y CONFIG_IOMMU_SUPPORT=y CONFIG_IOMMU_IOVA=y CONFIG_AMD_IOMMU=y CONFIG_AMD_IOMMU_V2=m CONFIG_INTEL_IOMMU=y CONFIG_INTEL_IOMMU_FLOPPY_WA=y
Thanks a lot.
I use xl dmesg this command I found this message.
(XEN) [ 0.478742] AMD-Vi: IOMMU 0 Enabled. (XEN) [ 1.670562] xenoprof: Initialization failed. AMD processor family 23 is not supported
I know IOMMU is support at XCP-ng 7.6.But cpu not support it.
@akong77 The error seems to point out that "xenoprof Initialization failed".
Do you have issue in creating or bringing your VMs online?
Do you see any error on VM start?
And was that VM working when you were on 7.5?
@r1 Only one can't start is show "virtual disk could not be found".I deattach disk and delete this vm.And re-create new vm then attach orig disk.It's all ok.
This VM can running on 7.5 because I first xcp-ng version is 7.5. I use import to xcp-ng from virtualbox.
I want upgrade to 7.6 because it's will restart system when use xcp-ng 7.5. But I don't know what problem.I think maybe AMD CPU support problem or IOMMU.So, I upgrade it.
I don't think its related to AMD CPU Support.
You just have to attach the disk correctly and mark it bootable via
If it still fails, check your
OK,whatever is all ok.
xenoprof: Initialization failed. AMD processor family 23 is not supported
Could any solution?
I have that on my Intel processor too. Everything works fine.

Just got a Ryzen 2700X in the lab. Everything works fine (I just lost 10min to find the "VMX" option to enable it in the BIOS)
