hello all, I have been trying to set-up bridged network with VLAN and not able to succeed as many tutorials address only single NIC. I am trying to setup 2 guests (backtrack instance) each guest has NIC1 and NIC2. following is snippet for guest1 I am not able to get 192.168.0.2 address back on guest eth0.

I normally try not to ask questions until I have done as much research as possible, and again, this is the case...

...um_pages. But, is "struct virtio_balloon_config"->num_pages updated when leak_balloon() is called via out_of_memory() ? Below explanation assumes that your answer is "no". I consider that fill_balloon() is using __GFP_NORETRY is a bug. Consider an extreme situation that guest1 is started with 8192MB memory and then guest1's memory is reduced to 128MB by virsh qemu-monitor-command --domain guest1 --hmp 'balloon 128' when VIRTIO_BALLOON_F_DEFLATE_ON_OOM was not negotiated. Of course, 128MB would be too small to operate guest1 properly. Since update_balloon_...

...the manageability of LVM within my DomU''s without actually using LVM within them." --------- I have the same situation from this post, which I think is the Best approach for manageability of disk space on Xen domains. I have a VG called vm_guests and 03 LV''s on it: lv_guest1_root, lv_guest1_swap, lv_guest1_export. I have them mapped on my xen config file: disk=[ ''phy:/dev/vm_guests/lv_guest1_root,xvda2,w'', ''phy:/dev/vm_guests/lv_guest1_swap,xvda1,w'', ''phy:/dev/vm_guests/lv_guest1_export,xvda3,w'...

HI all, Is it possible to install a virtual guest (FreeBSD and OpenBSD mainly) from kvm host's console? I have tried to do some search about this but I haven't found anything about it. My idea is to launch "virsh start guest1" and inmediately "virsh console guest1", but it doesn't works until serial console is configured inside guest .... Any tip? Thanks.

Gang, ???? I run several KVM host machines.? Due to updates, maintenance, and unexpected reboots sometime host machines are restarted.? I can easily envision a scenario where HostX needs some critical packages updated or is acting up.? I migrate guest0, guest1, guest2 etc. from HostX to HostY.? Then, in either a planned (i.e. scheduled maintenance) or unplanned (i.e. unplanned reboot) event reboots HostX. Unfortunately guest0, guest1 and guest2 are all set to autostart on HostX but they're currently running on HostY when HostX boots.... etc etc etc...

...r 3 logical volumes from the host system for its filesystem (/, /var, /data) and I have logical volumes named within the host system by guest and mount point so that I know what each logical volume is assigned to by it's name. 3. I expanded a specific logical volume on the host (/dev/vg/lv_guest1root) that is used by Guest1, and I can see in vgdisplay and lvdisplay that the logical volume was properly expanded. 4. I then issued a resize2fs /dev/vg/lv_guest1root command (on the host) to resize the filesystem to the expanded logical volume. This resulted in a message that it essentia...

Hi Rich, We just talked about a new tool virt-diff which can diff files between two guest, suggested by Kamezawa Hiroyuki <kamezawa.hiroyu at jp.fujitsu.com> things like below, # virt-diff -Nru --guest=Guest0 --guest=Guest1 /etc/hosts Any thought about this? Another question, what do you think about implement iptables, firewall, yum, rpm, etc into libguestfs? Thanks, Wanlong Gao
