[Xen-users] Xen-unstable (Error: Unable to connect to xend)
Hi, I have installed xen3.0.4.1 from source and every thing works well. Now I need to upgrade to xen-unstable. It is compiled and installed successfully (at least it seems to be) and I''m able to boot and run dom0. But Xend does not work. "xend start" gives no warning or error but running "xm list" I see: Error: Unable to connect to xend: No such file or directory. Is xend running? Regarding to some previous posts on the list I have deleted /lib/usr/python/xen and rerun make install but there is no improvement. Also I have rerun make all, make install in the tools directory but no improvement! Is there any other solution for this? Thanks in advance, Parissa. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
hi I use xen-3.0.3 ,and when I try to xm mem-set domU ,it does not work as I expected I boot up the domU with the config file mem=256 then I xm mem-set domU 128 ,and it works well , that is, xm list shows domU''s mem =128 and in the domU,/proc/meminfo is 128M but when I xm mem-set domU 512, it does not work well though the xm list shows domU''s mem =512 , but in the domU ,/proc/meminfo is 256M ,not 512M does xm mem-set can not expand domU''s memsize beyond its boot-size? or what should I do ? could you help me Thanks in advance _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

You may want to try "xm mem-max" to alter maxmem, but I read it is not the safest to use.

Thank you for your reply I try to use the commands of xm mem-max and xm mem-set ,and these both seems work well and you say "xm mem-max" is not safe , then what do you mean ? could you help me Thanks in advance Dominik Klein 写道:>> I boot up the domU with the config file mem=256 >> then I xm mem-set domU 128 ,and it works well , >> that is, xm list shows domU''s mem =128 and in the domU,/proc/meminfo >> is 128M >> >> but when I xm mem-set domU 512, it does not work well >> though the xm list shows domU''s mem =512 , but in the domU >> ,/proc/meminfo is 256M ,not 512M >> >> >> does xm mem-set can not expand domU''s memsize beyond its boot-size? or >> what should I do ? > > Set > maxmem=512 > memory=256 > in your config file. > > xm mem-set cannot go above maxmem. > > You may want to try "xm mem-max" to alter maxmem, but I read it is not > the safest to use. > > Regards > Dominik > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
