This article will introduction how to copy file beteew sysadmin-vm/xr-vm/host at IOS XR 64bit system.
First of all, we need to know how to access these 3 modules.
XR-VM
Login one device by using telnet, you can use command “dir” to check what file are stored in this media.
User Access Verification
Username: xuxing
Password:
RP/0/RSP0/CPU0:9904-E_eXR#
RP/0/RSP0/CPU0:9904-E_eXR#
RP/0/RSP0/CPU0:9904-E_eXR#dir harddisk:
You can use below two method to access XR-vm linux kernel, and you will see the same file stored at /harddisk:/.
Option 1：
RP/0/RSP0/CPU0:9904-E_eXR#
RP/0/RSP0/CPU0:9904-E_eXR#run
Mon Jul 1 03:54:17.751 CDT
[xr-vm_node0_RSP0_CPU0:~]$
[xr-vm_node0_RSP0_CPU0:~]$
Option 2：
RP/0/RSP0/CPU0:9904-E_eXR#admin

Sysadmin-VM
You can use below method access sysadmin-vm，and admin vm linux kernel.
RP/0/RSP0/CPU0:9904-E_eXR#admin

sysadmin-vm:0_RSP0#
[sysadmin-vm:0_RSP0:~]$ssh 192.0.0.1 <<< ssh LC sysadmin ip address, you can access lc sysadmin-vm linux kernel.
Host
sysadmin-vm:0_RSP0# run
Mon Jul 1 09:03:36.526 UTC
[sysadmin-vm:0_RSP0:~]$
[sysadmin-vm:0_RSP0:~]$chvrf 0 ssh my_host
[host:~]$
[host:~]$
Special for NCS55 (fretta), use below method to login host VM:
[sysadmin-vm:0_RP0:~]$
[sysadmin-vm:0_RP0:~]$ssh 10.0.2.16
[host:0_RP0:~]$
[host:0_RP0:~]$
to LC host vm , you can also use ip 10.0.2.16, like below from 0/RP0 sysadmin vm to LC0/1 sysadmin vm then to LC1 host vm.
[sysadmin-vm:0_RP0:~]$
[sysadmin-vm:0_RP0:~]$ssh 192.0.8.1
Warning: Permanently added '192.0.8.1' (ECDSA) to the list of known hosts.
[sysadmin-vm:0_1:~]$
[sysadmin-vm:0_1:~]$ ssh 10.0.2.16
[host:0_LC1:~]$
[host:0_LC1:~]$
Copy file from sysadmin or host to xr-vm
We can see xr-vm and xr-vm linux kernel will use same file system, so if we can copy file to xr-vm linux kernel, then we can find it at xr-vm.
RP/0/RSP0/CPU0:9904-E_eXR#admin
sysadmin-vm:0_RSP0#
[sysadmin-vm:0_RSP0:~]$chvrf 0 ssh my_host
[host:~]$
[host:~]$ cd /var/
[host:/var]$ cd log/
[host:/var/log]$ tar zcvf test.tar * <<<<< tar all file and named test.tar
[host:/var/log]$ ls -l test.tar

[sysadmin-vm:0_RSP0:~]$sftp my_host

Or use below method:
RP/0/RSP0/CPU0:9904-E_eXR#admin
Mon Jul 1 04:21:27.469 CDT
xuxing connected from 127.0.0.1 using console on 9904-E_eXR
