[Xen-users] Works...?! All blocked

Hello again,

now my xen works. But a strange thing:

Name                              ID Mem(MiB) VCPUs State  Time(s)
Domain-0                           0     2514     4 r-----    76.2
vx1                                1      256     1 -b----     6.1
vx2                                2      256     1 -b----     5.8
vx3                                3      256     1 -b----     5.3
vx4                                4      256     1 -b----     5.7
vx5                                5      256     1 -b----     5.2


All domains are in state blocked?! Possibile? I''ve difficulty to login
throught ssh and xm console DomID ... sometimes a virtual machines
seems to be freezed...

An error on my config?



Thanks
Stefano

Yes, it is possible that they are blocked, but it is very rare :S.

>  how is your configuration? and your system?
Hardware is: 2 Xeon 3.06 Ghz, 4gb RAM, HW RAID controller.

Debian sarge with xen 3.0.2 from backports.

My vx1 has config:

kernel = ''/boot/vmlinuz-2.6.16-2-xen-686''
ramdisk = ''/boot/initrd.img-2.6.16-2-xen-686''
memory = 256
name   = ''vx1''
root   = ''/dev/sda1 ro''
disk   = [ ''file:/vx/domains/vx1/disk.img,sda1,w'',
''file:/vx/domains/vx1/swap.img,sda2,w'' ]

# network
vif=[ '''' ]
dhcp="off"
ip="virtual_IP"
netmask="255.255.255.192"
gateway="physical_system_IP"
hostname="vx1.my.domain"

extra="3"



That''s my last 50 lines of /var/log/xend.log

Now, I''ve rebooted my physical system. I''m not able to login

vm. Ssh failed, xm console DomID failed.

So, very bad!
