[Xen-users] xenconsole: Could not read tty from store: No such file or directory
Has anyone seen this error before? I had a domU that was working fine before the reboot of the dom0. It did not autostart on the reboot even though it was configured to do so. A manual start got it part way through the kernel startup and then nothing. Any subsequent restart commands give only [root@gratia01 xen]# xm create -c xen5.cfg Using config file "./xen5.cfg". Started domain gratiax15 xenconsole: Could not read tty from store: No such file or directory the domU stays active until destroyed, but nothing happened. As far as I can tell there''s nothing in the xen database about this domain. I went so far as to delete the domain from the xen database (preserving the config file elsewhere) and then re-instantiate it, no difference. Any idea what might be going on?

PS--I did not say earlier, that when the xm create is listed, I get the pygrub prompt to select kernel and only then does the xenconsole prompt come up.

Re: [Xen-users] xenconsole: Could not read tty from store: No such file or directory
There were two problems: 1) the devices for /dev/xvc0 (virtual console) and /dev/xvda2 (swap) were somehow missing in this domU. I had already fixed that before I had sent this E-mail but that was why it didn''t autostart on bootup. 2) Once I did that, I had to restart xend to get the system to activate the domU again successfully and then all was well.
