[Fedora-xen] Cannot erase unsuccessfully created guests
Hello, list. I''ve been playing with Xen lately and it was only until yesterday that I could successfully create a guest with Fedora 8 installed on it (the one with name _cero_). The problem is that all the previous attempts have generated _records_ that I cannot erase. The following is from the terminal: [root@alfa11 gkeller2]# virsh list Id Name State ---------------------------------- 0 Domain-0 running 10 cero blocked [root@alfa11 gkeller2]# /usr/sbin/xm list Name ID Mem VCPUs State Time(s) Domain-0 0 1237 2 r----- 3085.3 cero 10 256 1 -b---- 728.5 fedora0 256 1 0.0 guest0 256 1 0.0 vm0 512 1 0.0 xen0 512 1 0.0 zero 256 1 0.0 [root@alfa11 gkeller2]# virsh destroy xen0 error: Failed to destroy domain xen0 [root@alfa11 gkeller2]# /usr/sbin/xm destroy xen0 [root@alfa11 gkeller2]# /usr/sbin/xm list Name ID Mem VCPUs State Time(s) Domain-0 0 1237 2 r----- 3086.2 cero 10 256 1 -b---- 728.6 fedora0 256 1 0.0 guest0 256 1 0.0 vm0 512 1 0.0 xen0 512 1 0.0 zero 256 1 0.0 [root@alfa11 gkeller2]# It seems virsh doesn''t detect those records, but xm does. Also, virsh cannot destroy them (what makes sense if it cannot see them), neither can xm. My problem is that, as far as I know, those _records_ of failed guest have memory assigned from dom0 and they affect the creation of new guests. Any suggestions? Thank you in advance, Gaston -- La única verdad es la realidad.

Re: [Fedora-xen] Cannot erase unsuccessfully created guests
Hi Gastón, First, these 512 of mem are just reserved to xen0 if when it starts. So, you don''t have this memory problem. And the option ''xm destroy'' is just to shutdown a cracked VM (I''m almost sure). To erase the VM you need to do ''xm delete''. Hope I helped.

So, you > don''t have this memory problem.I considered there was a problem because when I just created dom0, it''s assigned memory was around 2000. Later on, each time I created (or tried to create) a new guest, the amount of memory assigned to dom0 was being reduced. Now, I have used the command _xm_delete_ with each of the guest without id and they were effectively removed. My only concern now is that the amount of memory of dom0 hasn''t augmented accordingly. Am I misunderstanding something?> > And the option ''xm destroy'' is just to shutdown a cracked VM (I''m almost > sure). > To erase the VM you need to do ''xm delete''.Thanks for this. I didn''t know of the existence of that command. As far as I can tell, it is not documented in the manual pages (accessed from the terminal).
