aws ec2 xen hvm dracut centos 7 latest
Posted: 2018/09/10 12:00:20
Centos Gurus, pls bear with me.
Looks like something is fundamentally broken, or I am really dumb when it comes to centos understanding. Lets assume the latter
No matter how I recreate centos 7 latest -- vmdk s and import into aws, I run into the the following.
I researched a bit and seems red-hat had dropped xen support in the latest kernel builds (kernel-xen), I dont know, but I am having tough time in manually tweaking every vm copy I create and test until it runs on aws ec2 (I usually choose hvm).
Any better way to troubleshoot and recreate base images from my vbox? How do I add xen drivers to latest centos 7.? (heard of centos plus kernels), but is that a long term solution?
Unfortunately AWS doesnt provide console to work with dracut directly. As such by the time I stop and detach the disks, the
/run/initramfs/rdsosreport.txt" is gone. or am I missing something? Thanks a million in advance!!!
