XenGT_Setup_Guide

[Bill32]

hi,
would you offer a new XenGT_Setup_Guide? It seems not suit for the new repo now.
thanks.

[vmmqa]

sure, we are working on it, will update it ASAP, to be ready tomorrow.

[vmmqa]

updated. please have a try.

[Bill32]

I just followed the guide,then I saw warning below, I'm not sure this is an important warning or not.

root@new:/XenGT-Preview-kernel# mkinitramfs -o /boot/initrd-vgt-3.17.0-rc4-vgt.img 3.17.0-rc4-vgt+
grep: /boot/config-3.17.0-rc4-vgt+: No such file or directory
root@new:/XenGT-Preview-kernel#

Should I copy and rename .config to /boot and enter command like this "mkinitramfs -o /boot/initrd-vgt-3.17.0-rc4-vgt.img -v 3.17.0-rc4-vgt+" ?

[vmmqa]

does NOT matter. keep going. :)

[Bill32]

I updated UUID and root partition according to my environment and added the new grub entry in /boot/grub/grub.cfg .

I saw "error: no such disk. Press any key to continue" when I rebooted.
and "VFS: Cannot open root device "(null)" or unknown-block(0,0): error -6".

[vmmqa]

Double check this line? “set root='hd0,msdos1'”
Maybe his default grub option is not hd0, msdos1, for example hd1,msods5.

and double check the UUID number

[Bill32]

I have checked these, seems no wrong.
Detail imformation is as below:

root@new:~# blkid
/dev/sda1: UUID="eee4f0b8-06ee-4675-a258-07e625cc3056" TYPE="ext4"
/dev/sda5: UUID="278799a4-b74d-4c10-afa3-3170c0352ff3" TYPE="swap"

[vmmqa]

sees fine. please check if there is any typo.

[Bill32]

I don't think there is any typo and I have checked again.
I have tried many times, everything seems well except this warning:

---

I just followed the guide,then I saw warning below, I'm not sure this is an important warning or not.

root@new:/XenGT-Preview-kernel# mkinitramfs -o /boot/initrd-vgt-3.17.0-rc4-vgt.img 3.17.0-rc4-vgt+
grep: /boot/config-3.17.0-rc4-vgt+: No such file or directory
root@new:/XenGT-Preview-kernel#

Should I copy and rename .config to /boot and enter command like this "mkinitramfs -o /boot/initrd-vgt-3.17.0-rc4-vgt.img -v 3.17.0-rc4-vgt+" ?

---

I just Installed Basic Packages in Ubuntu, Built Kernel and Built Xen and Qemu. Then I just typed the new menuentry in the grub.cfg according to the guide and my evironment , rebooted.
Should I do any other operation after add menuentry to grub.cfg ?

[l1viathan]

Hi Bill32, xengt should only matter when xen_vgt.vgt=1 in the kernel cmdline is set. Please make sure that with "xen_vgt.vgt=0", your new kernel boots.

The configuration provided in this repository is FYI only, you may want to customize it according to your hardware/environment.

[Bill32]

I can boot now with "xen_vgt.vgt=0" in the kernel cmdline.

[Bill32]

hi,
Thank you for your advice, now I can run windows7 guest and install display driver. But I can't connect the network(I have configured Xen Bridge). I don't know why, would you help me? Thank you very much!
