Hello people of good will!

I'm trying to install the xen hypervisor in my system using this sequence:

https://help.ubuntu.com/community/Xen

My system:

joao@SERVER:/$ uname -a

Linux SERVER 4.18.0-13-lowlatency #14-Ubuntu SMP PREEMPT Wed Dec 5 12:12:14 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

It supports SVM, although i don't know what svm_lock is.

joao@SERVER:/$ egrep '(vmx|svm)' /proc/cpuinfo

flags       : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm constant_tsc rep_good nopl nonstop_tsc cpuid extd_apicid aperfmperf pni pclmulqdq monitor ssse3 fma cx16 sse4_1 sse4_2 movbe popcnt aes xsave avx f16c rdrand lahf_lm cmp_legacy **svm** extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw skinit wdt tce topoext perfctr_core perfctr_nb bpext perfctr_llc mwaitx cpb hw_pstate sme ssbd sev ibpb vmmcall fsgsbase bmi1 avx2 smep bmi2 rdseed adx smap clflushopt sha_ni xsaveopt xsavec xgetbv1 xsaves clzero irperf xsaveerptr arat npt lbrv **svm_lock** nrip_save tsc_scale vmcb_clean flushbyasid decodeassists pausefilter pfthreshold avic v_vmsave_vmload vgif overflow_recov succor smca

And after i did:

$ sudo apt-get install xen-hypervisor-amd64

and rebooted, this message appeared:

joao@SERVER:/$ xl list

ERROR:  Can't find hypervisor information in sysfs!

And when i tryed to boot on the Xen hypervisor entry at grub, it crashes and gives a glitchy login workspace that does not work.
After some research i've found that it may be a grub boot problem, several tutorials lead me to check this folders:

joao@SERVER:/boot$ ls

abi-4.18.0-10-lowlatency                  memtest86+.elf

config-4.18.0-10-lowlatency               memtest86+_multiboot.bin

config-4.18.0-13-lowlatency               retpoline-4.18.0-10-lowlatency

efi                                       System.map-4.18.0-10-lowlatency

grub                                      System.map-4.18.0-13-lowlatency

initrd.img-4.18.0-10-lowlatency           vmlinuz-4.18.0-10-lowlatency

initrd.img-4.18.0-13-lowlatency           vmlinuz-4.18.0-13-lowlatency

initrd.img-4.18.0-13-lowlatency.old-dkms  xen-4.9-amd64.efi

memtest86+.bin                            xen-4.9-amd64.gz

And:

joao@SERVER:/etc/grub.d$ ls

00_header        08_linux_xen   20_linux       30_os-prober      40_custom  README

05_debian_theme  09_lowlatency  20_memtest86+  30_uefi-firmware  41_custom

It was advised to do a move operation using some files that doesn't exist in my system:

joao@SERVER:/etc/grub.d$ mv -i /etc/grub.d/10_linux /etc/grub.d/50_linux

mv: não foi possível obter estado de '/etc/grub.d/10_linux': Arquivo ou diretório inexistente

I've tried to locate:

joao@SERVER:/$ locate 10_linux

joao@SERVER:/$ locate 50_linux

And both return nothing. How to proceed? is there a place to download those files? Any other tips on the next steps, thanks!
