- The system was running Xen and had two VMs.
- I don't know why, but I have not seen any "cannot allocate memory" since the update.
- I can't change anything right now >> because I've opened a ticket with Novell and waiting to hear back. >> > > Let us know how it goes.. > >> The
I installed Xen on it and created two paravirtualized linux boxes. It is intended solely for the individual or entity to whom the email was addressed. I have both of those mem settings set, so I don't think that's my issue. Otherwise, # this should be a space-separated sequence of regular expressions; any host # with a fully-qualified domain name or an IP address that matches one of # these regular expressions
I'll keep that in mind. Return non-zero if lock is # available. # path /
Great! Anyway, after cloning a VM today in Xen, I tried to start the DomU, and got this error: Error: (12, 'Cannot allocate memory') I assumed it had something to do with In my systems I use the same value eg : (dom0-min-mem 2048) (enable-dom0-ballooning no) in xend-config.sxo and multiboot /xen-3.4.gz /xen-3.4.gz noreboot dom0_mem=2048M in grub.cfg. System so far has been stable, however on reboot this time i've been affronted with a strange new error that appears only whilst booting hvm domains. (12, ‘Cannot allocate memory') However
You can try doingxm mem-set Domain-0 524288to shrink dom0's memory to 512MB. Each attempt results in the following error: # xm create /etc/xen/marzen Using config file "/etc/xen/marzen". Please confirm if the problem is resolved with allow_unsafe=on.

Basically when memory ballooning is set, the memory available to the main hypervisor will have a minimum value set and will balloon according to the current requirements. I had had that problem after a system upgrade where the "menu.lst" (or grub.fcg) was recreated without the tuning parameters.

I have tried using balloon to adjust memory on Dom-0, and while that works (xm list shows the new amount being used), it does not allow me to create any new

It is also often useful to use the parameter "dom0_min_mem=xxx" in the xend.config file.

This setting is in the config file which for me is at /etc/xen/xend-config.sxp: 1234# Dom0 will balloon out when needed to free memory for domU. # dom0-min-mem is the lowest memory I saw something about that setting a long time ago, but I always use it. HostB could not acquire a # lock for vm1 since the NFS server holds an exclusive lock # acquired by HostA. Reboot the server to set the memory for dom0.

I ask because the cannot allocate memory error can take a long time to show up. Thanks Comment 6 Andrew Jones 2013-03-19 10:49:08 EDT The last update to this BZ was almost two months ago.
